If the volume of a cylinder is 75pi cubic inches and the height is 3 inches then what is the radius of the base of the cylinder?

Answers

Answer 1

Answer: The formula for the volume of a cylinder is:

V=π*r²*h

We already know that...

V=75π
&
h=3in
so we can solve for the radius

V=π*r²*h
75π=π*r²*3
Divide both sides by pi
75=r²*3
Divide both sides by 3
25=r²
find the square root of both sides
5in=r

The radius of the base of the cylinder is 5in

Answer= 5in.

when you add all of the totals together your total amount will be $35.875

8 3/8 + 12 1/8 + 15 3/8

8 + 12 + 15 = 35
3/8 + 1/8 + 3/8 = 7/8

total = 35 7/8

Solve k + 4 - 2k - 24 > 0

Answers

k + 4 - 2k - 24 > 0
Subtract k from 2k
4 - k - 24 > 0
Add 24 to both sides
4 - k > 24
Subtract 4 from both sides
-k > 28
Divide -1 on both sides while flipping the inequality sign.
Final Answer: k < -28
