Answer 1

Answer:

Given:–

• Curved surface area of a right circular cylinder=22m²
• Radius of a cylinder,r=0.7m

To find:–

• Height of the cylinder,h=?

Answer:–

As we know that,

CSA of a cylinder=22m²

$2\pi rh = 22$

$2 \times \frac{22}{7} \times 0.7 \times h = 22$

$2 \times \frac{1}{7} \times 0.7 \times h = 1$

$h \times 0.1 \times 2 = 1$

$h = \frac{1}{0.2}$

$h = 5m$

So, The height of the cylinder,h=5m..
