The surface area of a sphere is given by the formula:
Surface area = 4𝜋r^2
We are given that the surface area is 7.84𝜋 square feet. Rearranging the formula, we have:
7.84𝜋 = 4𝜋r^2
Dividing both sides of the equation by 4𝜋, we get:
1.96 = r^2
Taking the square root of both sides, we find:
r = 1.4 feet
Therefore, the radius of the ball is 1.4 feet.
Find radius of ball that has a surface area of 7.84𝝅 square feet. (round to tenth and units)
