A cylinder has a radius of 5 cm and a height of 12 cm, what is the volume?

nika2105 [10]

Step-by-step explanation:

In a cylinder

Radius=r=5cm
Height=h=12cm

We know that

$\boxed { \sf \: volume = \pi {r}^{2} h} \\ \rm \rightharpoonup \: \frac{22}{7} \times {5}^{2} \times 12 \\ \rm \rightharpoonup \: \frac{22}{7} \times 25 \times 12 \\ \rm \rightharpoonup \: \frac{6600}{7} \\ \rm \rightharpoonup \: 942.8cm {}^{3}$
