A cylinder is a tree-dimensional figure with two parallel bases bounded by congruent circles and a curved lateral surface that connects the circles. The height, h, of a cylinder is the length of any perpendicular segment drawn from a point on the base to the plane containing the other base. A cylinder is a right cylinder if the segment joining the centers of the bases is perpendicular to the planes of the bases. Otherwise, the cylinder is oblique.
If a right cylinder has a height h and a base with radius r, then the lateral area L.A. is given by the formula: L.A. = 2(pi)(r)(h)
The surface area S.A. is given by the formula: S.A. = L.A. + 2(pi)(r^2).
Thus, the area of the cylinder's base is (pi)(r^2).

How do you find the surface area of a right cylinder?
The surface area formula for cylinders and prisms is SA = 2B + l where B is the area of your base l is your lateral area which is equal to l=ph where p is the perimeter (or circumference in your case) of the base and h is the altitude All cylinders have circular bases so the base area b = pi * r^2 where r is the radius of the circle the formula for circumference is 2*pi*r, where r is again the radius So, l = 2*pi*r*h And finally SA = 2*pi*r^2 + 2*pi*r*h This can be simplified to SA = 2*pi*r*(r+h)
The volume of a cylinder with a base of radius r is the area of the base times the length of its altitude h Which of the following is the formula for the volume of a cylinder?
v=pi.r^2h
How do you caculate the volume of a cylinder?
Volume of a CylinderThe volume of a cylinder is the product of the area of its base and its height. Because a cylinder has a circular base, the volume of a cylinder is: Pi x r squared x hwhere r is the radius of the circular base and his the height.
What is the formula for a sphere?
Surface Area=4/3*pi*r2 Where r=radius Volume= 4*pi*r3 Where r=radius There are NO equations for the area or the lateral area
How do you calculate this a right circular cone is inscribed in a hemisphere so that base of cone coincides with base of hemisphere what is the ratio of the height of cone to radius of hemisphere?
Suppose the radius of the sphere is R. The base of the cone is the same as the base of the hemisphere so the radius of the base of the cone is also R. The apex of the cone is on the surface of the hemisphere above the centre of the base. That is, it is at the "North pole" position. So the height of the cone is also the radius of the sphere = R. So the ratio is 1.
The base area of a cone or cylinder with radius r is B equals?
The base of a cone or cylinder is a circle. It the radius is r then the base area B=Pi(r2)
How do you find the surface area of a right cylinder?
The surface area formula for cylinders and prisms is SA = 2B + l where B is the area of your base l is your lateral area which is equal to l=ph where p is the perimeter (or circumference in your case) of the base and h is the altitude All cylinders have circular bases so the base area b = pi * r^2 where r is the radius of the circle the formula for circumference is 2*pi*r, where r is again the radius So, l = 2*pi*r*h And finally SA = 2*pi*r^2 + 2*pi*r*h This can be simplified to SA = 2*pi*r*(r+h)
The curved surface area of a cylinder is 6 22 7 r h find the area of its base?
Area of its circular base is pi*radius squared
How do you find the area of a circular base?
Area = πr2 where r is the radius of the base.
What is the surface area of a cylinder with base radius 33 and height 55?
Total surface area = 2*pi*r*(r + h) where r is the base radius and h the height.
How do you find the radius of a cylinder if only the base area and height are given?
Cylinders are effectively circular bases with height. Therefore, you can utilize the formulas for circles to determine the radius and diameter of a circle from the base area of a cylinder. The surface area of a circle is found by multiplying the radius^2 by pi. Hence, dividing the circle's surface area by pi will give you the r^2. Finding the square root of that number will give you the radius. For example: A cylinder with a base area of 78.5398163397448309615 inches would have an r^2 measurement of 25. Square rooting 25 yields a radius measure of 5 inches.
What are all the formulas you can use to find surface area of a right cylinder where h is the height r is the radius and BA is the base area?
It is 2*BA + 2*pi*r*h.Actually, if you have the radius or the base area, then the other piece of information is not required.
Volume for a cylinder?
Area of base x height = pi x r x r x h where r is the radius of the base and h is the height
How do you find the radius of a cone when you only have the area and slant height?
The surface area of a cone is the area of the base plus the area of the conical part. This is pi(r2 ) +pi(r)(s)=A If you have A and s, you can solve for r. ( s is the slant height and r is the radius)
What is the lateral area of a right cylinder if the radius of the base is 12mm and the altitude of the cylinder is 5 times the base radius?
2pi(r) multiplied by the height is lateral area of right cylinder. 2Pi(r) being the circumerfence of one of the bases.
What is the area of a cirle with a radius of 5 in?
The area of a circle of radius r is pi*r*r
How do you determine cubic foot in a cylinder?
