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:
x = 20
Step-by-step explanation:
The triangle is isosceles ( 2 congruent sides )
Hence the base angles are congruent, thus
3x = 60 ( divide both sides by 3 )
x = 20
The <em>correct answer</em> is:
Causation.
Explanation:
As the battery charge of a phone decreases, the amount of time you can perform any action with the phone decreases, including the number of minutes you can talk. This is because after a certain amount of time, there will be no more battery charge, which means you will not be able to use the phone at all.
