Step-by-step explanation:
height of the cylindrical tank = 20m
circumference of the tank = 39m
volumn of tank =
perimetre formula = 2πrh
= 2 x 3.14 x r x 20 = 39
= 188.4r = 39
r = 188.4/39
r = 4.83
volumn = πr^/2
h
= 3.14 x 4.83^2 x 2 x 20
= 1465.05
volumn of tank = 1465.05
LCD(12, 23, 54) = LCM(2, 3, 4) = 22×3 = 12
12 = 612
23 = 812
54 = 1512
The answer is A 22 square feet. first you have to convert 5.5 inches and 4 inches to feet.
