Question

The circumference of a great circle of a sphere is 44π. Find the Surface Area of the sphere.

Answer 1

1936 π square units

Explanation:

Given the information:

The circumference of a great circle of a sphere is 44π.

As we know the formula used to find a circle's circumference is:

C = 2πr , where r is the radius of the circle

In this situation, we know C = 44π

<=> 2πr = 44π

<=> r = 22 units

Hence, the Surface Area of the sphere

S.A = 4π
`r^(2)`

= 4π
`22^(2)`

= 1936 π square units
