1.	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» 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

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»

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
