What is the surface area of a sphere with a radius of 30 m? 1,800π m2 90,000π m2 3,600π m2 900π m2

The surface area A of a sphere:
\(A=4 \pi r^2\)
r - the radius

\(r=30 \ m \\ \\ A=4 \pi \times 30^2=4 \pi \times 900=3600\pi \ [m^2]\)

The surface area of the sphere is 3600π m².

Answer:

C. \(3600\pi \text{ m}^2\)

Step-by-step explanation:

We are asked to find the surface area of a sphere with a radius of 30 m.

We will use surface area of sphere formula to solve our given problem.

\(\text{Surface area of sphere}=4\pi r^2\), where r represents radius of sphere.

\(\text{Surface area of sphere}=4\pi*(30\text{ m})^2\)

\(\text{Surface area of sphere}=4\pi*900\text{ m}^2\)

\(\text{Surface area of sphere}=3600\pi \text{ m}^2\)

Therefore, the surface area of our given sphere is \(3600\pi \text{ m}^2\) and option C is the correct choice.
