Question

40. How much cloth 2.5 m wide will be required to make a conical ten
having base radius 7 m and h.
eight 24 m?​

Answer 1

Answer:

220 cloth

Step-by-step explanation:

It is given that Radius of the conical tent = 7m

Height of the conical tent = 24m

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 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.
