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.
The raduis.It's pi, r squared. the r stands for radius!
The area of a circle = pi*r2
A=pi(r)squared
area equals pi r squared therefor r squared equals area over pi. Now find square root of r squared and you have "R" (radius) = 2.821
Pi r squared is the formula for the area of a circle. 2 pi r squared is twice that.
SA=2(pi times r squared) + h(pi 2 r) or (easier way) 2 pi r squared + 2 pi r h
pi times the radius squared pi r squared
that is 14,519.4 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.
"Pi R Squared" refers to the formula for the area of a circle. A = (pi)r2 (3.1416 times the square of the radius)
Pi times r times r or Pi r squared is the formula for finding the area of a circle where r is the radius
No. 2Pi r is equal to Pi d, though.
The area of a circle = pi*r2
The raduis.It's pi, r squared. the r stands for radius!
