Answer 2

Answer:

Appropriate Question :-

• If the radius of the base of a cylinder is 7 cm and its height is 15 cm. What it is volume.

Given :-

• The radius of the base of a cylinder is 7 cm and its height is 15 cm.

To Find :-

• What is the volume of the cylinder.

Formula Used :-

$\clubsuit$ Volume of Cylinder Formula :

$\longmapsto \sf\boxed{\bold{\pink{Volume_{(Cylinder)} =\: {\pi}r^2h}}}$

where,

• r = Radius of the base of a cylinder
• h = Height of a cylinder

Solution :-

Given :

$\bigstar\: \sf Radius =\: \sf\bold{7\: cm}$

$\bigstar\: \sf Height =\: \sf\bold{15\: cm}$

According to the question by using the formula we get,

$\longrightarrow \sf Volume_{(Cylinder)} =\: \dfrac{22}{7} \times (7)^2 \times 15$

$\longrightarrow \sf Volume_{(Cylinder)} =\: \dfrac{22}{7} \times 7 \times 7 \times 15$

$\longrightarrow \sf Volume_{(Cylinder)} =\: \dfrac{22}{7} \times 49 \times 15$

$\longrightarrow \sf Volume_{(Cylinder)} =\: \dfrac{22}{\cancel{7}} \times {\cancel{735}}$

$\longrightarrow \sf Volume_{(Cylinder)} =\: 22 \times 105$

$\longrightarrow \sf\bold{\red{Volume_{(Cylinder)} =\: 2310\: cm^3}}$

$\therefore$ The volume of a cylinder is 2310 cm³.
