How do you find the area of a circle with a radius of 7?
The area of a circle is pi times the radius squared (A = π r²).
When the circumference is 7 feet the radius is how many feet?
Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation.
