Question

Curved surface area of a right circular cylinder is 4.4m . If radius is 0.7r
find its height.​

Answer 1

Answer:

h = 1 m

Step-by-step explanation:

Curved Surface Area of Cylinder = 2πrh

Placing the values in the formula we get,

4.4 = 2 × π × (0.7) × h

2.2 = π × (0.7) × h

2.2 = 22/7 × 0.7 × h

After simplifying we get,

h = 1 m

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

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