The area of a circle is pi times r squared.

Pi r 2. Pi is a numerical constant roughly 3.142. r is the radius of a circle. 2 in this case is the square of the radius. All this adds up to the area of a circle. Area=Pi x (radius squared)

R means radius because the area of a circle = pi*radius2

SA=2(pi times r squared) + h(pi 2 r) or (easier way) 2 pi r squared + 2 pi r h

Pi r squared is the formula for the area of a circle. 2 pi r squared is twice that.

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

You mean what Is the circumference of a circle? pi*(r)squared.

i think you do ~ (thats pi) ~r2 ( pi r squared but its been a while since ive done this type of math

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

pi times the radius squared pi r squared

That would depend if you mean 2 times the radius times pi (2*pi*r) or the more likely scenario pi times radius squared (pi*r2). 2*pi*r is the formula of the circumference of a 2d circle. Pi*r2 is the formula of the area of a 2d circle.

A = 'pi' 'r' squared in this case r = 6 r squared = 36 pi = 3.14 so A or area, is = 36(3.14)

The raduis.It's pi, r squared. the r stands for radius!

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

The area of a circle = pi*r2

square root of x/pi

"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 r squared comes from the formula to find the area of a circle.

Area = pi*radius2A = Pi*R-squaredPi * R^2

volume of a circle

the area of a circle

A=pi(r)squared
