Question

Find the total surface area if its radius 50cm and height 45cm

Answer 1

Answer:-

= 11000 cm²

Given:-

height = 45 cm

radius = 50 cm = 50/2 = 25 cm

We have to find here Total Surface Area

The formulae of Total Suraface Area of cylinder is  2πr (h+r)

Total surface area =  2πr (h+r)

Here,

h is hieght

r is radius

π value is 22/7

⇒ 2πr (h+r)

⇒ 2 × (22/7) × 25 × (45+25)

⇒ 2 × (22/7) × 25 × 70

⇒ 2 × 22/7 × 1750

= 11000 cm²

Total surface area is 11000 cm²
