The surface area of a sphere is 7.84π ft.2 What is the radius of this sphere?(1 point)
To find the radius of the sphere, we need to use the formula for the surface area of a sphere:
Surface Area = 4πr^2
Given surface area = 7.84π ft^2
7.84π = 4πr^2
Dividing both sides by 4π:
r^2 = 7.84/4
r^2 = 1.96
r = √1.96
r = 1.4
Therefore, the radius of the sphere is 1.4 feet.
