A semi-circular

A semi-circular fishbowl is filled with water and has a diameter of 10 feet. What is the total weigh of water to the nearest pound in the tank, if water weighs 62.5 pounds per cubic foot?

Correct answer:

m =  16362 pd

Step-by-step explanation:

D=10 ft ρ=62.5 pd/ft3  r=D/2=10/2=5 ft V1=43 π r3=43 3.1416 53523.5988 ft3 V=V1/2=523.5988/2261.7994 ft3  m=ρ V=62.5 261.7994=16362 pd
