Question

if the base radius of a cirular cylinder is 22cm3 and its height is 10xm then its volume is?​

Answer 1

Given:-

• Base radius of a circular cylinder = 22cm

• It's Height = 10cm

To Find:-

• Volume of the circular cylinder.

Formula Used:-

• ${\boxed{\bf{{Volume\:of\: Cylinder= \pi r^2h}}}}$

Solution:-

Using Formula,

$\tt :\implies\: Volume\:of\: Cylinder= \pi r^2 h$

$\tt :\implies\: Volume\:of\: Cylinder= \dfrac{22}{7}\times 22^2 \times 10$

$\tt :\implies\: Volume\:of\: Cylinder= \dfrac{22}{7}\times 4,840$

$\tt :\implies\: Volume\:of\: Cylinder= \dfrac{1,06,480}{7}$

$\tt :\implies\: Volume\:of\: Cylinder= 15211.42\:cm^3$

Hence, The Volume of Cylinder is 15211.42cm³.

Answer 2

Answer:

The formula for the lateral surface area of a right circular cylinder is 2πr*h, where r is the radius of the circular base and h is the height of the cylinder.

So, if the length of the radius of the base is 12 cm and the height is 21 cm, the lateral surface area of the cylinder is:

2π x 12 x 21 = 864π cm^2.

It's important to note that the lateral surface area of a cylinder is the sum of all its side surfaces, but not including the circular top or bottom surfaces.

In case you want to calculate the total surface area of cylinder, it would be 2πr^2 + 2πr*h, where r is the radius of the base and h is the height of the cylinder.

So, in this case, it would be:

2π x 12^2 + 2π x 12 x 21 = 1,456π cm^2.
