The surface area of a sphere is 7.84π ft.2 What is the radius of this sphere?(1 point)

Answer 1

The surface area of a sphere is given by the formula 4πr^2, where r is the radius. We can set up the equation:

4πr^2 = 7.84π ft^2

Dividing both sides of the equation by 4π, we get:

r^2 = 1.96 ft^2

Taking the square root of both sides, we find:

r = 1.4 ft

Therefore, the radius of the sphere is 1.4 ft.
