Question

The circumference of the circular base of a cylinder is 44 cm and its height is 15 cm. The volume of the cylinder is 

A. 1155 cm³ 

B. 2310 cm³ 

C. 770 cm³ 

D. 1540 cm³

Answer 1

Given that, 

Height = 15 cm 

Circumference = \(2\pi r\)

r = \(\frac{44\times7}{2\times22}\)

= 7 cm 

We know that, 

Volume of cylinder = \(2\pi r\)

= \(\frac{22}{7}\times7\times7\times15\)

= 2310 cm³ 

Hence, option B is correct
