Question

the curved surface area of a cone of radius 8 cm is 352 cm^2. find its height.

please tell me the answer.​

Answer 1

Given that :

• Radius 8cm
• Curved surface area of cone → 352cm²

Find:-

• Height.

Solution

Formula :-

$\boxed{ \sf CSA \ of \ cone = \pi rl}$

R is radius

l is height.

$\sf \implies 352cm^2 = \dfrac{22}{7} \times 8 \times l \qquad\qquad ...[Taking \ \pi \ as \ \dfrac{22}{7}]$

$\sf \implies\dfrac{352cm^2 \times 7}{22 \times 8} = l$

On solving it, we get

$\sf \implies l = 14cm$

Therefore, the height of the cone is 14cm.

Hope it helps!
