To find the radius of the sphere, you can use the formula for the surface area of a sphere:
Surface Area = 4πr^2
where r is the radius of the sphere.
Given that the surface area is 7.84π ft^2, you can equate this to the above formula and solve for r:
7.84π = 4πr^2
Divide both sides of the equation by 4π:
7.84π / 4π = r^2
2 = r^2
Taking the square root of both sides, we find:
r = √2
Therefore, the radius of the sphere is approximately 1.41 ft, not 1.40 ft.
The surface area of a sphere is 7.84π ft.2 What is the radius of this sphere? is it 1.40
