Question

A circular tent is cylindrical to the height of 4 cm and conical above it if its diameter is 105 m and its slant height is 40 m then find the required total area of canvas

Answer 1

the total area of canvas is 6732m

Answer 2

The required total area of canvas is 6613.2 sq.m.

Step-by-step explanation:

1 m = 100 cm

Height of cylindrical part = 4 cm = 0.04 m

Diameter of cylinder = 105 m

Radius of cylinder = $\frac{105}{2}=52.5m$

Curved surface area of cylinder = $2 \pi r h = 2 \times \frac{22}{7} \times 52.5 \times 0.04=13.2 m^2$

Slant height of cone = 40 m

Radius of cone = 52.5 m

Curved surface area of cone = $\pi r l = \frac{22}{7} \times 52.5 \times 40 =6600 m^2$

Total area of canvas required = $6600+13.2 = 6613.2 m^2$

Hence the required total area of canvas is 6613.2 sq.m.
