62 x pi2 = 611.9154729 = 611.9 (1 decimal place.) It's 611.915471469109395.

pi times the radius squared pi r squared

the same as pi squared, which is 9.86960440109

The square root of pi times pi is simply pi. Because pi*pi=pi squared, the squared and the square root will cancel each other, leaving just pi.

Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)

Area=pi times radius squared Circumference=pi times diameter or pi times radius times two

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.

(pi times radius squared) plus (pi times radius times slant).

The area of a circle is: pi times radius squared

That is correct because the surface area of a sphere is: 4*pi*radius squared

Area is pi times the radius, squared. And circles are two-dimensional. There is no volume. But for cylinders, the area is pi times the radius squared, times two, times the height.

The area of a circle is pi times (radius squared) Thus if radius is one inch then area is (pi) times (1) times (1) = pi = 3.1416 inches squared
