You will get pi since area of a circle equals pi* times radius squared....by Mona Martinez
Divide the area by pi and then square root it this will give the radius of the circle.
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.
That depends on what you know. If you know the radius of the circle, double it to get the diameter. If you know the circumference of the circle, divide it by π to get the diameter. If you know the area of the circle, find its square root and divide the result by π to get the radius then multiply by 2 to get the diameter.
Divide the area by Pi. Take the square root of the result. This is the radius. Now double the radius to get the diameter. -> Answer = 18
What do you have? The area of the circle or the circumference? Area: divide the area by pi, then square root it Circumference: divide the circumference by 2 then divide it by pi
divide the square feet by pi that gives you the radius squared find the square root and get the radius
you divide the circumference by pi to get diameter then divide that by 2 to get radius then square the radius and multiply it by pi

Divide the area by the value of Pi - then divide that result by 2 !

Divide the area by pi then square root your answer which will give the radius of the circle and use 2*pi*radius to find the circumference.

Divide the diameter by 2 to get the radius then square the radius, and finally multiply by pie (3.14)
If you have the diameter, then the formula for the area of a semi-circle is:(pi x (diameter/2)2)/2That is,Divide the diameter in two to find the radius (diameter/2)Square the radius (radius x radius)Multiply it by pi (3.1416)Divide the answer by two to find half the circle.Remember your units. The answer will be in square inches, or square centimeters or square somethings.
What do you have? The area of the circle or the circumference? Area: divide the area by pi, then square root it Circumference: divide the circumference by 2 then divide it by pi
For a circle, the area is pi x radius squared. If 5 is the diameter, divide it by 2 first to get the radius. Pi is about 3.14.
