Answer 1

Answer:

EXPLANATION.

Circumference of the base of cylinder = 44.

Sum of its radius and height = 27 cm.

As we know that,

Circumference of the base of cylinder = 2πr.

⇒ 2πr = 44.

⇒ 2 x 22/7 x r = 44.

⇒ 2 x 22 x r = 44 x 7.

⇒ 44 x r = 44 x 7.

⇒ r = 7 cm.

Sum of its radius and height = 27 cm.

⇒ r + h = 27.

⇒ 7 + h = 27.

⇒ h = 27 - 7.

⇒ h = 20 cm.

As we know that,

Formula of :

Total surface area = 2πr(r + h).

⇒ 2 x 22/7 x 7 (7 + 20).

⇒ 2 x 22 (27).

⇒ 2 x 22 x 27.

⇒ 1188cm².
