Answer:
answer C is the right one
Step-by-step explanation:
Volume cylinder is area of the (round) surface * height.
The formula for the area of any circle = pi * radius²
pi * radius²
So the formula for the volume is
Volume cylinder = pi * radius² * height
radius = 15 in and height = 6 in
Substitute this in the formula and you get:
Volume cylinder = pi * 15² * 6
Volume cylinder = pi * 225 * 6
Volume cylinder = pi * 1350
so answer C is the right one
Answer:
28 minutes
Step-by-step explanation:
we know that
1) A factory manufactures a metal piece in 32 minutes
2) New technology allowed the factory to cut that time by 8%
Remember that

In this part 32 minutes represent the 100%
To find out how long it take to manufacture the piece, multiply 32 minutes by the factor 0.92

3) Then another improvement cut the time by 5%
Remember that

In this part 29.44 minutes represent the 100%
To find out how long it take to manufacture the piece now, multiply 29.44 minutes by the factor 0.95
