Which value is the radius of a circle with an 8-foot diameter?

Explanation:
Radius is half the diameter. With an 8-foot diameter, the radius is 8 ÷ 2 = 4 feet. So the radius is 4.0 ft. The other numbers would pair with diameters of 7 ft, 9 ft, or 10 ft, which don’t match the given 8-foot diameter.
