ANSWER
C) V=πr²h
EXPLANATION
The formula for calculating the volume of a prism is

where B represents the area of the base and h represents the height of the prism.
A cylinder is a prism with a circular base.
Therefore area of the base is

Therefore the volume of the cylinder is

The correct choice is C.
Answer:
l = gt²/(2π)²
Step-by-step explanation:
if T = 2π√l/g
squaring both sides
(T)² = (2π)² × (√l/g)²
T² =4π² × l/g
T² = 4π²l/g
using cross multiplication techniqes
gT² = 4π²l
divede both sides by " 4π²"
gT²/4π² =4π²l/4π²
gT²/4π² =l
l = gT²/(2π)²
that is the final answer.
Answer:
1 3/10
Step-by-step explanation:
9/8 +7/40
Get a common denominator of 40
9/8 *5/5 + 7/40
45/40 + 7/40
52/40
Rewriting as
40/40 +12/40
1 + 3/10
1 3/10
Answer:
It will take the worm 7 days to get to the top of the well.
Step-by-step explanation:
the well is 37 feet deep
the worm climbs up 7 feet, but loses 2 feet through the night
That means the worm only really climbs 5 feet a day.
So, if you subtract 5 from 37, 6 times, you'll get 7 feet left to go. And sense the worm climbs 7 feet a day, the last day the worm will climb his way to the top without slipping back down.
Hopefully this makes sense.
