kljdsf/////////////////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.
