Answer:
= 1397 cm2
Step-by-step explanation:
We have,
Diameter of cylinder = 7 cm
So, Radius of cylinder = 7/2 cm
Height of cylinder = 60 cm
By using the formula,
Curved surface area of cylinder = 2πrh
= 2 × 22/7 × 7/2 × 60
= 1320 cm2
Total surface area of cylinder = 2πr (h+r)
= 2 × 22/7 × 7/2 (60 + 7/2)
= 22 (127/2)
= 1397 cm2
