A cylindrical water tank near the town library is 20 meters high and has a circumference of 39 meters. What is the approximate v
olume, to the nearest whole number, of the water tank? Use 3.14 as an approximation for π and round to the nearest whole number.
1 answer:
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
