Question

Curved surface area of a right circular cylinder is 4.4m square if the radius of the base of the cylinder is 0.7m find its height and volume​

Answer 1

Answer:

$\huge \fbox \green{answer}$

Given:

⇒R=0.7m

⇒CSA=4.4 m2

Let's assume height be x

⇒2πrh=4.4 m2

⇒2×722×0.7x=4.4

⇒x=2×22×0.74.4×7=1m

⇒Height =1m

Let the height of the right circular cylinder be h m.

r=0.7m

Curved surface area = 4.4m²

$\longrightarrow$ 2πrh=4.4

$\longrightarrow$ 2 × $\small\dfrac{22}{7}$ × 0.7 × h = 4.4

$\longrightarrow$ 4.4h = 4.4

$\longrightarrow$ h = 1m

$\small\sf\pink{Hence, \: the \: height \: of the \: right \: circular \: cylinder \: is \: 1m}$
