Water reservoir

The reservoir shape of a cylinder having a diameter 8 m and a height 2.8 m. The device indicates that the reservoir contains 800 hectoliters of water. Calculate how much % of volume is used.

Correct answer:

p =  56.8411 %

Step-by-step explanation:

V1=800/10=80 D=8 h=2.8 r=D/2=8/2=4 V2=π r2 h=3.1416 42 2.8140.7434 p=100 V1/V2=100 80/140.7434=56.8411%
