Question

The c.s.a of a triangle is 1210 and its diameter is 10cm . find the height?

Answer 1

Given diameter = 10cm.Then the radius will be r = 5 cm.

Given Curved surface area = 1210

We know that Curved surface area = 2pirh

                                               1210 = 2 * 22/7 * 5 * h

                                                h = 1210 * 7/2 * 22 * 5

                                                   = 38.5 cm.


Hope this helps!
