What is Pi R Squared?
The formula to get the area of a circle ("R" being the radius of the circle). Radius means the distance from the center of the circle to the edge.It means pi times radius squared which is the formula for finding the area of a circle.
What is the formula of finding the radius of a rectangle?
Hell are you talking about?!? A radius is a dimension of a circle! A rectangle has no stinking radius!
What is the formula for finding an area of a circle?

What is formula ofr finding area of a circle?
Area of a circle = pi*radius squared
What is the radius and the area of a circle?
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
