Answer:
Total surface area of a cylinder = 2πr(h + r)
(Taking π = 3.14)
2 ×3.14×7.5(20+7.5)
47.1 × 27.5
=1,295.25 CM square.

Answer:
942 6/7 cm³
Step-by-step explanation:
Hey mate!
This is the step by step explanation
As we all now the formula of C.F.A( curved surface area ) of cylinder is 2πrh Now
π= 22/7
= 2 X 22/7 X 7.5 X 20
= 2 X 22/7 X 150
= 44/7 X 150
= 6600/7
= 942 6/7 cm³
