Question

Can anyone find the answer????

Answer 1

Your answer should be A.

Explanation:

To begin, you must acknowledge the formula for the SA or Surface Area of a Cylinder. Which is: 2πrh+2πr2

Now, we plug it in!

2π4×10 + 2π16

How do I know this?

Your radius if 4, since it's half of the cylinder. Since the second part calls for your radius squared, you must do 4x4.

Answer 2

A≈351.86 or rounded to the nearest tenth, 351.9.
