Answer:
Option A = 113.04in^2
Step-by-step explanation:
Question: What is the total surface area of the cylinder? If the radius is 2in and height is 7in.
A) 113.04 in.2
B) 100.48 in.2
C) 131.88 in.2
D) 69.08 in.2
Solution:
Total surface area of a cylinder = 2πr^2 + 2πrh
r = radius = 2in
h = height = 7in
Let π = 3.14
Total surface area of the cylinder =
2×π×2^2 + 2×π×2×7
= 8π + π×28
= 8×3.14 + 3.14×28
Total surface area of the cylinder = 113.04in^2
=113.04in^2 (option A)
Answer: -416/1575
Step-by-step explanation:
Answer:
-8
Step-by-step explanation: since it says Times, (for me times is multiplication) you would multiply -2 and 4. negative 2 would be from that person losing 2 points. and 4 since it is your total amount of times you have forgotten to write your name. so, -2 x 4 = -8.
how i got -8. both signs from -2 and 4 are different, and when they are different the answer will always be negative.

Especially since the shape is convex
