Answer 2

Given,

The conical tent height = 45cm.

Base diameter of the tent = 36cm.

The number of tents = 50.

Price for canvas  =9.4 rs per m².

To Find,

The total cost of the canvas.

Solution,

Given that,

The tent's shape is conical.

It has a height of forty-five cm.

The diameter of the tent is 36cm.

Let's find the area for one tent.

A = $\pi r(\sqrt{r^{2} +h^{2} })$

A = 3.14×18×$\sqrt{18^{2}+ 45^{2} }$

A = 56.52×$\sqrt{2349}$

A = 2739cm²

For the canvas per area, it required rupees 9.4.

Area of fifty tents = 2739 × 50

136950m².

The total money needed for 50tents = 136950× 9.4

1287,330rs.

The total money is 1287,330rs.
