The area of a circle is 81 pi square feet What is the radius?

The area is 9 feet. You find the square root of 81 which is 9. I want circumference, not area.


How do you find the radius of a circle inside a square?

The same as half the side of the square, as the radius of the circle is half its diameter, and the diameter of the circle is equal to the side of the square.


How many square feet are in 29 feet in diameter?

The formula for square footage of a circle uses the constant pi (roughly a value of 3.14) in its calculation and the length of the radius of the circle. Area of a circle equals radius x radius (R squared) x 3.14 (pi). If we are given that information that the circle is 29 wide (diameter), we know enough to find the answer. Since radius (R) equals 1/2 of diameter, divide 29/2=14.5 14.5 x 14.5 x 3.14= 660.18 square feet in a circle 29 feet in diameter.


How do you find the radius of an inscribed circle of a square given the area of the circle?

If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)


How do you find the radius of a square?

A square does not have a radius. A square, with sides of length x units, can have an inscribed circle. Such a circle would have a radius of x/2 units. Or the square could have a circumscribing circle. This would have a radius of x/sqrt(2) units.


The area of a circle is 154 square meters Find the radius?

How do you find the radius of the base in a cylinder?

It depends on the values you have. The base of a cylinder is a circle. If you know the circle's diameter, half it to find the radius. If you know the circle's circumference, divide by 2pi to find the radius. If you know the circle's area, divide by pi and take the square root to find the radius.


How do you find the circumfrence of a circle if you have the radius?

the circumfrence of a circle is pi times it's radius squared.
