The surface area of a sphere is 7.84𝝅 ft^2
What is the radius of the sphere?
The surface area (A) of a sphere is given by the formula A = 4𝜋r², where r is the radius of the sphere.
We are given that A = 7.84𝜋 ft².
Substituting this value into the formula, we have:
7.84𝜋 = 4𝜋r²
Dividing both sides of the equation by 4𝜋, we get:
7.84𝜋 / 4𝜋 = r²
Simplifying:
1.96 = r²
Taking the square root of both sides, we find:
r = √1.96
Therefore, the radius of the sphere is approximately 1.4 feet.
