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.
