Question

a conical tint of 56m base diameter require 3080sq m of canvas for csa then find the vertical height ​

Answer 1

Step-by-step explanation:

Given:In a conical tent, 56 in diameter & required area of canvas for the surface 3080cm².

To find:

The height of the conical tent.

Explanation:

We have,

Diameter of conical tent= 56cm

Radius of the conical tent= 56/2= 28cm

Area of the curve surface of cone=3080cm².

•Using Formula of the curved surface area of the cone: πrl

Now,

Using formula of the slant height:

l² = r² + h²

h² = l² - r²

h² = [35² - 28²]cm

h² = 1225cm - 784cm

h² = 441cm

h= √441cm

h= 21cm

Thus,

The height of the conical tent is 21cm.
