Answer:
to find the volume of a cylinder
V=π x r^2 x h
now since we want the whole figure were going to add up the two heights to get one height number 4ft + 5ft = 9ft
V= 3.14 x 3^2ft x 9ft
V= 3.14 x 9ft^2 x 9ft
V= 254.34

Answer:
900
Step-by-step explanation:
perimeter: P = 2w + 2h
P = 2(20) + 2(25)
P = 40 + 50
P = 90
Multiply perimeter by 10:
90 × 10 = 900
