Question

the circumference of the base a cylinder is 15 m and its height is 84 m findthe volume

Answer 1

Circumference of base of cylinder =15m(given) height =84m(given) we have to find its volume so, we have circumference =15m this implies = 2 pi r =15(r =radius),, =2.22/7.r=15=r=2.38m so, r=[2.38m], now volume of cylinder =pi r2h (h=height) therefore, it's volume=1495.4016m3.

Answer 2

Answer:

1503.409 m^3

Step-by-step explanation:

Volume of cylinder = Area of base * Height

2*π*r = 15

π*r = 15/2

(22/7)*r = 15/2

r = (15*7)/(22*2)

Area = π*r^2

(22/7)*((15*7)/(22*2))*((15*7)/(22*2))

Area = 17.89

Volume = 17.89 x 84

Volume = 1503.409 m^3
