What is the area and circumference of the circle

The area of the circle is going to be 50.27 because the equation for the area of a circle is pie • r^2 and the radius is 4 feet because radius is half the diameter and the circumference of the circle will be 25.13 because the formula for circumference is 2• pie • r

Area would be 50.27 because the formula for the area is pie • r• r which the radius is 4 feet. Then the circumference would be 27.13.
