Depends on what level of math you're on, the most simple of ways to explain is this: If you were to divide the circle into many pieces using the radius, let's say eight pieces. You then rearrange them into a parallelogram and each base is half of the circumference. The height of it is the radius, and using the method to find a parallelogram, BxH=A.

How do you work out pi r squared?

That is the formula for the area of a circle; r refers to the radius, and pi is approximately 3.14. r squared means that you multiply r x r.

What is pie r squared?

"Pi R Squared" refers to the formula for the area of a circle. A = (pi)r2 (3.1416 times the square of the radius)


What is the radius of a circle with an area of 2826?

the formula for the area of a circle is pi times r squared (sorry this website does not work today for presenting this better) so 2826 = pi times r squared so dividing through on both sides bi pi gives you: 2826 divided by pi = r squared so r is the square root of (2826/ pi) 2826/pi = 899.5437384 so r is the square root of 899.5437384 = 29.99239468 r = 29.99 (to 2 decimal places)


What is pi r r?

Pi times r times r or Pi r squared is the formula for finding the area of a circle where r is the radius


Is 2Pi r the same as Pi r squared?

No. 2Pi r is equal to Pi d, though.


What is the relationship between the area of a circle and its radius squared?

The area of a circle is defined by the equation A = πr^2 where π = pi (3.14...) A = Area r^2 = radius squared So, the radius of a circle squared multiplied by pi equals the area.


What is formula for pi r squared?
