Find the volume of the following cylinder.

(a)

(b)

Answer:

(a) Radius of cylinder = \[\frac{7}{2}\] =3.5 cm

Height of cylinder = 10 cm

\[\therefore \]      Volume of cylinder \[=\pi {{r}^{2}}h\]

\[=\frac{22}{7}\times 3.5\times 3.5\times 10\]

= 385 \[c{{m}^{3}}.\]

(b) Base area of cylinder = 250 m3

Height of cylinder = Base area \[\times \] height

= 250 \[\times \] 2

=500m3.
