Question

there is a tent in form form cylinder submounted by a cone find its area .points ke bhikhari answer na de for boys only this line is ​

Answer 1

Answer:

1319.47m²

Explanation:

Area of canvas required for the tent = Curved surface area of the cylindrical portion + Curved surface area of the cone

=(π)rl+2(π)rh

For cylinder:

Radius (r) of the cylinder =14 m

Height(h) of the cylinder =7m

Curved surface area of cylinder =2πrh=2(π)×14×7=196(π)

For cone:

Radius (r) of the cone =14m

Slant height of the cone =5m

Curved Surface area of cone =πrl=π(14)(5)=(70π)m²

Hence, area of canvas =(196π+70π)m²

=(266π)m²

=420×(22/7)

=1319.47m²

It seems you've been asking this question for too long so....
