The surface area of a sphere is 7.84π ft.² What is the radius of this sphere?
(1 point)
The formula for the surface area of a sphere is 4πr², where r is the radius of the sphere.
Given that the surface area of the sphere is 7.84π ft.², we can plug this value into the formula and solve for r:
4πr² = 7.84π
r² = 7.84/4
r² = 1.96
r = √1.96
r = 1.4
Therefore, the radius of the sphere is 1.4 feet.
