Question

How much cloth 2.5 m wide will be required to make a conical tent having base radius 7 m and height 24 m?

Answer 1

Answer:

It is given that

Radius of the conical tent = 7m

Height of the conical tent = 24m

We know that

We know that Slant height l =√ (r2 + h2)

We know that Slant height l =√ (r2 + h2) By substituting the values

l = √(72 + 242)

On further calculation

l = √(49 + 576) = √625

So we get

l = 25 m

We know that

We know that Area of the cloth = πrl

By substituting the values

Area of the cloth = (22/7) × 7 × 25

On further calculation

Area of the cloth = 550 m2

We know that

Length of the cloth = area/ width

By substituting the values

Length of the cloth = 550/ 2.5 = 220m

Therefore, 220m of cloth is required to make the conical tent.
