Question

the circumference of the base of a conical tent is 44 cm .If the height of the tent is 24 cm .Find the length of the canvas used in making the tent if width of canvas is 2 m

Answer 1

Let h be the height of the conical tent r be the radius  of its base  B be the width of the canvas Circumference  of base=44 2*pie*r=44 R=44*7/44 R=7m l=sqrt (9*7+44*44)=5 Area of canvas =csa  of cone L*B=pie*r*l L=22*5*7/7*2=55m Thus the length of canvas used 55m
