Answer:
207.24 in.
(This is not a rounded answer)
Step-by-step explanation:
So, this will be very fun, simple, and easy!
First thing we do is use this formula, A(s) = 2πrh + 2πr²
We don't know the surface area yet, and that's what we are looking for, so first off we go ahead and plug in the radius, which is 6 divided by 2, and that's 3! The height is 8 inches!
Let's plug in 3.14 for pie too.
A(s) = 2(3.14)3(8) + 2(3.14)3²
Let's start solving.
A(s) = 150.72 + 2(3.14)3²
3 squared is 9!
A(s) = 150.72 + 56.52
A(s) = 207.24 inches
So, the answer is...207.24 in.! THat is the correct answer, but if I'm wrong, please comment so I can change my answer! Thanks for the points, have a great day or else!
