Question

The curved surface area of a cone is 4070 cm2 and diameter is 70 cm .What is its ***** height? (Use π =22/7)

Answer 1

Diameter of the cone(d) = 70 cm

So, radius of the cone(r)= diameter/2

= 70/2 cm

= 35 cm

Curved surface area = 4070 cm2

Now,

We know,

Curved surface area = πrl

So,

πrl = 4070

22/7 x 35 x l = 4070

or l = 37

Therefore, ***** height of cone is 37 cm.
