Given data
Volume v = ?
Diameter d=
?
Radius r = 
Height h= 
we know that the volume of a cylinder is expressed as

Substituting our given data we have

The first cylinder as a volume of 
The change in volume is 
percentage =

Answer:
1. 520
2. 568.125
Step-by-step explanation:
1.
10 per 40 hours + 1.5 overtime
1.5 overtime = 10(1.5) = 15
10 (40) + 15 (8)
= 400 + 120
= 520
2.
11.25 per 40 hours + 1.5 overtime
1.5 overtime = 11.25(1.5) = 16.875
11.25 (40) + 16.875 (7)
= 450 + 118.125
= 568.125
