Question

a right circular cylinder has a height of 1 m and radius of 35 cm find its volume area of curved surface and total surface​??
please give me answer.....................

Answer 1

Answer:

Volume of cylinder =385000 cubic cm

Curved surface area of cylinder = 22000 sq.cm.

Total surface area of cylinder = 29700 sq.cm.

Step-by-step explanation:

Height of cylinder = 1 m = 100 cm

Radius of cylinder = 35 cm

Volume of cylinder =\pi r^2 h = \frac{22}{7} \times 35^2 \times 100=385000 cm^3πr2h=722×352×100=385000cm3

Curved surface area of cylinder = 2 \pi r h = 2 \times \frac{22}{7} \times 35 \times 100 = 22000 cm^22πrh=2×722×35×100=22000cm2

Total surface area of cylinder = 2 \pi rh + 2 \pi r^2 = 2\times \frac{22}{7} \times 35 \times 100 + 2 \times \frac{22}{7} 35^2=29700 cm^22πrh+2πr2=2×722×35×100+2×722352=29700cm2

Curved surface area of a right circular cylinder of height 35cm is 121cm^2. Find the radius of the base.
