My father installed a cylinder-shaped pool in the garden with a bottom diameter of 6 m and a height of 1.5 m. how many hectoliters of water can fit in the pool? How many m2 of space must be cleaned after draining the pool?

Correct answer:

V =  424.115 hl
S =  56.5487 m2

Step-by-step explanation:

D=6 m h=1.5 m  r=D/2=6/2=3 m  S1=π r2=3.1416 3228.2743 m2  V1=S1 h=28.2743 1.542.4115 m3  V=V1 hl=V1 10  hl=42.4115 10  hl=424.115 hl=424.115 hl
S=S1+π D h=28.2743+3.1416 6 1.5=56.5487 m2
