Answer 1

Answer:

$\large\bold\pink{○ANSWER:}$

Given:-

Let, r be the radius and h be the height of the cylinder.

To Find:-

◎ The diameter of the base of the cylinder

Formula used:-

Curved surface area = 2πrh

Solution:-

$= 2 \times \frac{22}{7} \times r \times 14 = 88$

$⇝88r = 88 {cm}^{2}$

$⇝r = \frac{88}{88}$

$⇝r = 1cm$

○ then diameter = 1 × 2 = 2cm

∴ The Diameter of the base of the cylinder is = 2cm

Answer 2

$\huge\bold\blue{❥ ANSWER: }$

⇒ 2πrh=88

⇒ 2× 722

×r×14=88

⇒ r= 2×22×1488×7

⇒ r=1

⇒ 2r=2

Hence, diameter of the base is 2.
