What is the diameter of the circle that has a circumference equal to its area?
The diameter is 4 and its radius is 2 because 2+2 = 4 and 2 squared = 4 Circumference of the circle: pi*4 is the same as pi*2 squared Area of the circle: pi*2 squared
How do you find the area of a sphere?
4 * pi * radius * radius or (pi * diameter * diameter) / 3 Also ( 4 * 3.14 * radius squared ) Also ( 88/7 * radius squared )
What is the answer of pi squared?
pi squared = approximately 9.8696044
What is pi squared times pi?
n squared x n = n cubed but that does not equal 21. ---------------------------------------------------------------- Here is the correct version: We are looking for Pi squared times Pi which is Pi cubed Now Pi can never be written out exactly because its decimal number goes on for ever. However we can take a good approximation to Pi as 3.142 So Pi cubed = 3.142 x 3.142 x 3.142 = 31.018339 = 31.02 to 4 places.
Does sphere have a surface?
Yes and its formula is: 4*pi*radius squared
