hi there

maths legends

The curved surface area of a cone is 4070cm2and its diameter is 70 cm. What is its slant height?

Answer 1

Hey,



I had completed the sum in this photo .



Hope it may help you.

Answer 2

$\mathfrak{The\:Answer\:is}$


Given diameter = 70 cm

2r = 70 cm

r = 35 cm

Now...curved surface area = 4070 cm 2

=> πrl = 4070 cm ^ 2

where....

r = radius and l = slant height


Therefore..

πrl = 4070

=> 22/7 * 35 * l = 4070

=> l = 37 cm
