The surface area of a sphere is 7.84 pi ft² what is the radius of this sphere
The surface area of a sphere is given by the formula:
Surface Area = 4πr²
where r is the radius of the sphere.
We are given that the surface area is 7.84π ft², so we can set up the equation:
7.84π = 4πr²
Dividing both sides by 4π, we get:
r² = 1.96
Taking the square root of both sides, we find:
r = √(1.96) ≈ 1.4 ft
Therefore, the radius of this sphere is approximately 1.4 feet.
