The formula for finding the area of any circle is pi*radius2..
Pi is the number you have to use to solve many circle equations. If you want to find the area of a circle, use radius squared times pi. For the circumference, use diameter times pi.
You use the formula A=(pi)r^2 solve for r which will give you the square root of A/pi. In your case the area has pi already in it so it is just 2 times the square root of 8.
The surface area of a sphere can be calculated with the formula: A = 4[pi]r2 Plug in r: A = 4[pi](8)2 And solve: A = 256[pi]
With pi rounded to 8 digits, it is 24.000008.

Calculate: C = pi times r.
You use the formula A=(pi)r^2 solve for r which will give you the square root of A/pi. In your case the area has pi already in it so it is just 2 times the square root of 8.
The surface area of a sphere can be calculated with the formula: A = 4[pi]r2 Plug in r: A = 4[pi](8)2 And solve: A = 256[pi]
4 times pi times 4 divided by 2 is 78.9568352087
With pi rounded to 8 digits, it is 24.000008.
c=pi*8 diameter = 8 radius = 4 area = pi * 16
The formula where C=circumference, R=radius is C = 2 pi R Since C = 16 pi inches and 16 pi = 2 pi R we can solve for R and get R= 16 pi /2 pi = 8 Therefore the Radius is 8 inches.
