A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

How do you find the base of a cone?

The base of a cone is the area basically so : pi(radius)^2


What is the formula to find total area of a cone?

Curved Surface Area of a Cone:Multiply the base radius of the cone by pi. Multiply your answer by the length of the side of the cone.Then add the surface area of the base of the cone using the area of a circle = pi x r2


What is the formula to find the surface area of a cone?

pi * r * s, where r is the radius of the base and s is the distance along the edge of the cone from the top to the base (not the height).


What is the area of hollow cone?

Find cone base area using a circle's formula, which is pi times (radius squared). Find cone slanted area with this formula:half of the length of the side, times the circumference of the base.. Add the results to get the total surface area.Measure the cone's circumference with this formula: C = pi * d. C is circumference and d is its diameter. Measure the diameter, which is a line from the base's one side, through its center, to the opposite side.Calculate cone slant height from its top to its base's side. Use your slant height and circumference measurement to calculate cone slanted area. Use step one's formula, where "s" is the slant height, and C is the circumference.4 Add your results for cone base area and cone slanted area to get the total cone surface area.


How do you calculate the area of a cone's base?

The base of a cone is a circle. The area of a circle is found by multiplying the diameter by Pi.


Can you find the volume of a cone?

Volume = Base x Height /3 Where base is the area of the base circle (pi*radius*radius) and Height is the perpendicular distance from the base to the apex of the cone


What is the formula to find the base of a cone?

the cone base formula


The volume of a cone varies jointly as the height of the cone and the area of the base The volume of a cone with height 30 centimeters and base 14 centimeters squared is 140 centimeters cubed Find t?

A+ = 28 centimeters cubed


How many bases does cone have?

A cone does not really have a base but if you find the circumference of the bottom that is the base.


How do you find the cubic centimeters of a cone?

A cone has 1/3 the volume of its cylinder. To find the volume multiply the area of the circular base (pi times radius squared) and multiply it by the height of the cone. That is the volume of the cylinder with the same dimensions. Divide this number by 3 to find the area of the cone. Use unit ratios to make sure your answer is in cubic centimeters.


How do you calculate the surface area of a cone?

find the surface area of the cone and add it to the surface area of the base so the formula would be pi radius s plus pi radius squared


What is the volume of a cone with area of the base 100 and height 6?

A cone with a base area of 100 and a height of six has a volume of 200 units3


What is the formula for measuring the cylinder volume of unequal circles?

It's a frustum! to find the area of this figure you need to take the area of the entire cone and subtract the area of the mini cone. Let me explain.If you keep extending thesideofthe figure into the direction of the smaller circle, it creates a cone, right? so take volume (1/3 area of base * height) of the entire extended cone (whose base is the bigger circle to the vertex). Then take the volume of the top cone(whose base is the small circle to the vertex). Subtract the small one from the big one, and it gives you the area of the frustum.


What is the formula to find the slant height of a cone?

area base hight


Does a cone with a circle base and a cone with a square base have the same volumes?

no The area of a cone is 1/3 times the base times the height, so the volumes are the same only if the area of the base times the height is the same in both cones.

A cone with height 24 and the base diameter 7 has a surface area of 305.17 units2


How do you find the curved surface area of cone?

Suppose you have a cone with slant height='l' and base radius 'r' and perpendicular height 'h' Curved surface area of COne=pi*r*l =pi*r*(squareroot(r2+h2))


What is the formula for the area of a cone?

The formula for the area of a cone is one-third multiplied by the base multiplied by the hight.


The cross sectional area of a cone parallel to the base is twice the base area?

No. They are the same.


What is the derivation of the formulae of the surface area of a cone?

You can approximate the surface area by lots of triangles (base of the triangle on the base of the cone, and tip of the triangle at the tip of the cone), and analyze what happens when the triangles get narrower and narrower.


What is the formula for the surface area of a cone?

Area = πSr + πr² Where: S = the slant length of the cone r = radius of the base πr² = area of the base of the cone πSr = area of outside of cone -------------------------------------------------------------- The surface area of the cone is the sum of the area of the base and the slanted surface. The area of the base is the area of a circle = πr² The area of the slanted surface can be calculated by realising that if the slanted surface is cut by a straight line from the apex to the base it can be "unrolled" into a sector of a circle. Thus it is a fraction of the area of a circle. The length of the circumference of the sector is the length of the circumference of the base of the cone; the length of the whole circle from which this is a sector is the circle with radius of the slant height of the cone; thus: area slanted surface = πS² × ((2πr)/(2πS)) = πSr Thus the surface area of a cone = area base + area slant surface → surface_area_cone = πr² + πSr = πr(r + S) where r is the radius of the base and S is the slant height.


How to find the volume of a right circular cone with a base radius of 3ftand a height of 9 ft?

The formula for the volume of a right circular cone is: V = 1/3Bh where B is the base area and h is the height. Since the base is a circle, use pi r2, the formula for the area of a circle, to calculate the base area. Use 3.14 to approximate pi. The base area in this problem would be: 3.14(3)2 = about 28.26 sq. ft. Therefore the volume of the cone would be: 1/3(28.26)(9) = about 84.78 cu. ft.


How do you find volume of right circular cone?

You calculate 1/3 times the base area s the height. The height should be perpendicular to the base.
