Question

A right circular cylinder has a height of 1 m and a radius of 35 cm. Find its volume, area curved surface and total surface. ​

Answer 1

$\bf\large{Solution:}$

Height = 1 m

Radius = 0.35 m (35/100)

Volume =

πr²h

3.14×0.35×0.35×1=

0.38 m³

______________.

CSA =

2πrh

2×3.14×0.35×1=

2.19 m²

______________.

TSA =

2πr(h+r)

2×3.14×0.35×(0.35+1)

2.96 m²

______________.

Answer 2

Answer:

Volume= 385000cm³

Curved surface area =22000cm²

Total surface area=29700 cm²
