Area of a circle = (pi) x (radius)2
(pi) = about 3.1416 or about 22/7 . (It can never be written down exactly.)
(radius)2 = (radius) x (radius)

Is 1.7 the radius of a circle?
1.7 is a fine number. It can be the radius of a circle.Any number can be the radius of a circle.
How can you fine the cirumference of a circle?
The circumference of a circle: 2*pi*radius or pi*diameter
How do you find radius of a circle?
Draw a line from any part on the outside of a circle to the exact center of the circle. * * * * * That is fine if you know where the center is but not much use if you are just given a circle and do not know where the exact centre is. In this case: Draw a chord - a straight line joining any two points on the circumference of the circle. Then draw the perpendicular bisector of the chord. Draw another chord and its perpendicular bisector. The two perpendicular bisectors will meet at the centre.
How do you fine the area of a you shaped figure?
Well, it depends on the area of the shape you are trying to find, if its: square: length times width triangle: base times height divided by 2 circle: 3.14 times radius squared trapezoid: base 1 plus base 2 times height divided by 2 A U shaped figure is probably half of a circle and a rectangle. The diameter of the circle is the same as the width of the rectangle.
How do you fine the area of a triangle using sine?
Given two sides and the angle between them, you can use the formula: Area = 1/2*a*b*sinѲ Where a and b are the sides, and Ѳ the angle between them.
Is 1.7 the radius of a circle?
1.7 is a fine number. It can be the radius of a circle.Any number can be the radius of a circle.
How can you fine the cirumference of a circle?
The circumference of a circle: 2*pi*radius or pi*diameter
What is the area of a circle if the diameter is 40 feet?
Knowing that the formula to find the area of a circle is * Ac = πr2 We must first find the radius of the circle with this formula: * Rc = d/2 So dividing the diameter by two we get a radius of 20 feet. * 20' = 40'/2 Now that the radius is found, we can plug it in and fine the exact answer needed: * Ac = π(20ft)2 * Ac = π(400ft2) We find that the exact answer is 400πft2. However if you want to calculate out the the value by multiplying out π the answer would change from 400πft2 to approximately 1256ft2. π = pi π ≈ 3.14

Circumfrence of a circle?
to fine the circumference of a circle you take the radius of a circle and multiply it by pi which is 3.14 even thoush there is a like a million other nunbers in pi you only multiply it by 3.14
CSA of a cylinder is 176 cm2 and its base area is 38.5 cm2 find its volume?
find the radius using base area. substitute the radius value in CSA and fine the height. finally substitute radius and height in volume of cylinder formula and find the volume of the cylinder.. Ans:308 cu.cm.
What formula would you fine lateral area of a right cylinder where h is the height and r is the radius?
It is 2*pi*r*h square units.
What is the circumference of a circle?
The circumference is the distance around the circle, its "perimeter."The circumference of a circle is equal to π times the diameter of the circle (C = πd), or π times twice the radius of the circle (C = 2πr).The circumference is the distance around itIf you know the diameter (width) of the circle, you can use the formulaCircumference= Diameter x pi (approx 3.1416)Example : if a circle has a diameter of 5 cm then the circumference is 5 x π =5π (about 15.7 cm)The actual formula relates to the radius of the circle, which is half the diameter.Radius Formula : C = 2πr (2 pi times the radius)As long you remember the formula you should be fine....Circumference = 2 * pi * rOr pi * dwhere r = radius & d = diameter of the circle.Also pi (=3.143) can be roughly put down as 22/7 if you more comfy with fractions than the decimals.the equation is 2*pi*rr being the radius

Mention an area and we might have an answer for you. You have given NO information whatever about where this is happening.
Will vic fine that iceland is entirely north of the arctic circle?
No.
How do you fine the area of a triangle using sine?
Given two sides and the angle between them, you can use the formula: Area = 1/2*a*b*sinѲ Where a and b are the sides, and Ѳ the angle between them.
