Question

The radius of a conical tent is 7 meters and its height is 10 meters. Calculate the lenght of canvas used in making the tent if width of canvas is 2m(use phi = 22/7)
​

Answer 1

Answer:

please mark me as brainliest

step-by-step explanation:

Radius of a conical tent = 7m (Given)

Height of the conical tent = 10m (Given)

Width of the canvas = 2m (Given)

Surface area of the cone = πrl  

= 7 × 7+10 × 10

= 49+100

= 149

Since width of the canvas is 2, thus length -  

= 149/2

=74.5

Therefore the length of canvas used in making the tent is 74.5m.
