Question

The curved surface area of a cylinder is 216TT sq.cm. If its height is 18 cm,
its radius is​

Answer 1

Answer:

34.36 cm

Step-by-step explanation:

$csa \: of \: given \: cylinder = 216 \: \: {cm}^{2}$

$= > 2\pi \: \times \: rh = 216$

$= > 2 \times \frac{22}{7} \times r \times 18 = 216$

$= > r = \frac{216 \times 7}{2 \times 22}$

$= > r = 34.36$
