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:
Surface Area = 4πr^2
Where r is the radius of the sphere.
Given that the surface area is 7.84π ft^2, we can set up the equation:
7.84π = 4πr^2
Dividing both sides by 4π, we get:
1.96 = r^2
Taking the square root of both sides, we find:
r ≈ 1.4 ft
Therefore, the radius of the sphere is approximately 1.4 ft.
