Question

The total surface area of a cone having its slant height 9dm and dimeter of its base as 24dm. Find surface area.

Answer 1

Answer:

Hello dude here is your answer

slant height =9DM

and Diameter of its base is 28 DM

so radius = 14DM

we will find the surface area of cone

so the formula will we

$\pi \: rl + \pi {r}^{2}$

so 22/7×14×9 + 22/7 ×14×14

836+616

1452 DM

I hope you get your answer
