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.

How do you find the pi circumference and area of circles?
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
What is the area of 11 pi?
The area of a circle is: pi times radius squared
What is the area of a circle radius equal to 1?
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
What is formular of circle?
Area of a circle: pi times radius squared Circumference of a circle: 2 times pi times radius or diameter times pi
How do you get the circumfrence for a circle?
Pi times radius squared.
How do you find out the area of a circle?
pi times the radius squared pi r squared
What is pi times pi divided by pi plus pi minus pi times pi?
the same as pi squared, which is 9.86960440109
What is the square root of pi times pi?
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.
How do you use pi to determine circumference?
Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)
How do you find the pi circumference and area of circles?
Area=pi times radius squared Circumference=pi times diameter or pi times radius times two
What is Pi times r squared if r is sixty eight?
that is 14,519.4 squared
Surface area of cone?
(pi times radius squared) plus (pi times radius times slant).
What is the area of 11 pi?
The area of a circle is: pi times radius squared
What is 4 times pi times the radius squared is the surface area of a sphere?
That is correct because the surface area of a sphere is: 4*pi*radius squared
How do you get the area and the volume of the circle?
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.
What is the area of a circle radius equal to 1?
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
How do you work out a circles area?
pi times the radius squared or pi (approx 3.14) times the diameter
