HELP PLS MS SUE.
Find the surface area of a sphere with a radius of 8 cm.
a)267.9
b)803.8
c)2143.6
d)201.0
i think its a
SA = 4πr^2
SA = 4 * 3.14 * 8^2
B. is the correct answer.
Thank you so much bree and ms sue. could you help me with some more problems
You're welcome. I'll be glad to help you with your other problems.
Bree -- if you want to help, please show students how you arrived at your answer.
To find the surface area of a sphere, you can use the formula A = 4πr^2, where A is the surface area and r is the radius.
In this case, the radius of the sphere is given as 8 cm.
So, to find the surface area, substitute the value of the radius into the formula:
A = 4π(8^2)
Now, simplify and calculate:
A = 4π(64)
A = 256π
To get the final answer, you can either leave it in terms of π, or you can approximate it using a numerical value for π (such as 3.14 or 22/7).
If you choose to approximate using π ≈ 3.14, then the surface area is approximately:
A ≈ 256(3.14)
A ≈ 803.84 square centimeters
Therefore, the surface area of the sphere with a radius of 8 cm is approximately 803.84 square centimeters.
