Use the surface area formula for a cylinder! 2πrh+2πr2
Plug in what you know! (If the diameter is 8, then that means the radius is 4.)
r = 4
h = 12
2π(4)(12) + 2π(4)(12) = 402.12
I hope this helps! :)

Answer:
74
Step-by-step explanation:
Average is the sum of all the numbers divided by the number of numbers.
We will take average of Quizzes, Homeworks, and Tests. And multiply that by respective weights and find the weighted average of the 90%.
Quiz Avg:
(84+90+72)/3 = 82
Homework Avg:
(80 + 100 + 90)/3 = 90
Test Avg:
(64+72)/2 = 68
Now, weighted avg =
Rounding it off, we get "74", the correct answer.
Answer:
This is because to square a number just means to multiply it by itself. For example, (-2) squared is (-2)(-2) = 4. Note that this is positive because when you multiply two negative numbers you get a positive result.
