the equation for the volume of a conical tent is
v = 1/3 * height * area of the base
= 1/3 ×hπr²
where v - volume
h - height of the conical tent
r - radius of base circle
area of the base = 3v/h
πr² = 3 *968/7 m³ /4 m
r² = 3 * 968 * 7 / (7 * 22* 4 )
= 33
r = 5.74 m
area of the curved surface = πrl
where l is the slant height
l² = r² + h²
= 5.74² + 4²
= 33 + 16
= 49 m
l = 7 m
then the area of the curved surface is ;
area = πrl
= (22/7) * 5.74 * 7
= 126.28 m²
the canvas should have area 126.28 m² to cover the tent
