1.Firstly, determine the slant height of conical test by using the formula,

2.Further, using the formula for curved surface area =πrl which we get the required canvas.

In this question we have to find C.S.A of conical tent

so,firstly we have to find the l(length) of âˆ†

√h×h+r×r

√3.5×3.5+12×12

√12.5+144

√156.25

12.5

C.S.A. of conical tent=πrl

3.14×12×12.5
