Question

a circus tent is cylindrical upto a height of 3 m and conical above it.if diameter of the base is 105 m and the slant heightbpf the conical part is 53 m , then the total canvas used on making the tent is

Answer 1

total canvas used = πrl
= (22/7)× (105/2)×53
= 7745 m sq

Answer 2

Area of Canvas = area of cylinder + area of Cone

A= 2πrh + πrl

A= (2×22/7×105/2×3) +

( 22/7×105/2×53)

A= (22×15×3 )+(11×15×53)

A= 990 +8745

A=9735 sqm
