Question

Find the volume of a cylindrical tank of height 1.4m and circumference of base is 2πm.

Answer 1

Answer:

8.624m³

Step-by-step explanation:

circumference of base= 2πm = 2×(22/7)×(1.4×100) cm

circumference of base= 2×(22/7)×140cm

circumference of base=880cm

circumference of base= πD =880cm

so, πD=880

=> D = 880/(22/7)

=> D = 880×(7/22)

=> D = 280

as, D= 280 cm so, radius = 280/2 = 140 cm

Volume of the cylindrical tank = πr²h

Volume of the cylindrical tank = (22/7)×140×140×140 cm³

Volume of the cylindrical tank = [(22/7)×140×140×140]/(1000000) m³

Volume of the cylindrical tank = 8624000/1000000 m³

Volume of the cylindrical tank = 8.624m³
