The surface area of a sphere is 7.84π ft.2 What is the radius of this sphere?(1 point)
$$
ft.
To find the radius of the sphere, we first need to use the formula for the surface area of a sphere:
Surface area = 4πr^2
Given that the surface area is 7.84π ft^2, we can plug this value into the formula:
7.84π = 4πr^2
Dividing both sides by 4π:
r^2 = 7.84/4 = 1.96
Taking the square root of both sides:
r = √1.96 = 1.4
So, the radius of the sphere is 1.4 ft.
