The surface area of a sphere is 7.84 π ft.^2 what is the radius of those sphere
The formula for the surface area of a sphere is given by:
Surface area = 4πr^2
Given that the surface area is 7.84π ft^2, we can set up the equation as follows:
7.84π = 4πr^2
Dividing both sides of the equation by 4π:
r^2 = 7.84 / 4
r^2 = 1.96
Taking the square root of both sides to solve for r:
r = √1.96
r ≈ 1.4 ft
Therefore, the radius of the sphere is approximately 1.4 ft.
