Find the surface area of a sphere with a radius of 12 m.

A. 1,809 m^2
B. 452 m^2
C. 7,235 m^2
D. 603 m^2

Not sure? Please help!

SA = 4 * pi * r^2

surface area of a sphere=4πr^2

r=12

4π12^2
=1809m^2

option(A)

Yes, A.

Thank you both!

You are welcome, Amber.

To find the surface area of a sphere with a given radius, you can use the formula:

Surface Area = 4πr^2

where "r" represents the radius of the sphere.

In this case, the radius of the sphere is given as 12 m. So, we can substitute this value into the formula:

Surface Area = 4π(12)^2
= 4π(144)
= 576π

To get a specific numerical value, we can use an approximation for π, such as 3.14.

Surface Area ≈ 576 × 3.14

Calculating further, we get:

Surface Area ≈ 1,809.44 m^2

Now, looking at the given answer choices, the closest option is A. 1,809 m^2.

So, the correct answer is A. 1,809 m^2.
