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 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.
Do you multiply the radius or the diameter of pi?
The raduis.It's pi, r squared. the r stands for radius!
What is formula for pi r squared?
The area of a circle = pi*r2
How do you get area of a circle?
A=pi(r)squared
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 2 pie r sqaured?
Pi r squared is the formula for the area of a circle. 2 pi r squared is twice that.
How do you find the are of the base of a cylinder?
SA=2(pi times r squared) + h(pi 2 r) or (easier way) 2 pi r squared + 2 pi r h
How do you find out the area of a circle?
pi times the radius squared pi r squared
What is Pi times r squared if r is sixty eight?
that is 14,519.4 squared
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.
