Answer:
1539.38
Step-by-step explanation:
this can be figured out as an entire cylinder and then take 1/2 of that
area of a circle of 7 cm
area = [tex]\pi[/tex][tex]7^{2}[/tex]
area = 153.938
volume = 153.938 * 20
volume = 3078.7608
and take 1/2 of that to find volume of the half cylinder
3078.7608 / 2 = 1539.38
