Question

Find the volume of right circular cylinder whose height is 40 cm and semi-circumference of base is 66 cm​

Answer 1

To Find:-

The volume of right circular cylinder

Solution:-

$\green{Answer:}$

The volume of cylinder is 2640 cubic cm

Step-by-step explanation:

We know that

Circumference = 2 $\pi r$

Given that:-

Circumference of its base is 66 cm

By the question,

$\begin{gathered}2 \pi r = 66\\2 \times \frac{22}{7} \times r=66\\r=\frac{66 \times 7}{22 \times 2}\\r=10.5\end{gathered}$

So,

Height of cylinder is 40 cm

Volume of cylinder = $2 \pi r h = 2 \times \frac{22}{7} \times 10.5 \times 40=2640 cm^32 \pi rh$

$\green{Hence,}$

The volume of cylinder is 2640 cubic cm
