Question

Curved surface area of cone is 4670sq.cm and its diameter is 70cm.Find its slant height?

Answer 1

Hello Mate!

Curved surface area of cone = πrl

Curved surface area of cone = 4680 cm²

So radius = diameter / 2 = 70 cm / 2

4680 cm² = πrl

4680 cm² = 22/7 × 70/2 × l

4680 cm² = 110 × slant height

4680/110 = slant height

42.5 cm = slant height

Thanks!!!

Have great future ahead!
