Question

If the area of the base of a right circular cone is 3850 $c{m}^2$ and its height is 84 cm, find the slant height of the cone.

Answer 1

To find the CSA we need radius and slant height.
radius can be finded by GIVEN AREA OF BASE.
$\pi r^2$=3850

r=35
slant height can be finded by $L^2=R^2+H^2$

$L^2={35}^2+{84}^2$

$L^2$ = 1225 + 7056 = 8281

L = 91
