Question

The area of the curved surface of a cylinder is 6160cm. The height of the cylinder is 10cm. What is the radius of the cylinder in centimeters

Answer 1

Answer:

r = 98 cm

Step-by-step explanation:

Formula for curved surface area = $2\pi rh$

where r = radius & h = height

Let the radius be 'r'.

According to the question ,

$6160 = 2 \times \pi \times r \times 10$

$= > 20\pi r = 6160$

$= > r = \frac{6160}{20\pi} = \frac{6160 \times 7}{20 \times 22} = 98cm$
