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.
