The surface area of a sphere is 7.84 pie ft what is the radius of this sphere
The formula for the surface area of a sphere is given by A = 4πr^2, where A is the surface area and r is the radius.
To find the radius, we rearrange the formula: r = √(A/4π)
Plugging in the given value of surface area (A = 7.84π ft), we can calculate the radius:
r = √(7.84π/4π)
= √(1.96)
= 1.4 ft
Therefore, the radius of this sphere is 1.4 ft.
