Given: Radius=7cm,

Height=10cm

Total surface area=2πr(h+r)sq.units

=> 2× 22/7 × 7(5+7)

=> 528^2cm

.

Hope it helpful..✌️

Answer 2

Answer:

528 cm^2

Step-by-step explanation:

TSA = 2πr (h + r)

This is the formula for the total surface area of a given cylinder whose radius is r and height is h.

Height = 5

Radius = 7

2×22/7×7×(5+7)

2×22/7×7×(12)

44/7×7×12

528^2
