Find the slant height $l$ of a cone if radius $r = 20.2 cm$ and Curved Surface Area $CS A = 3513.9112 cm$ .

Answer

$55.3718$

Explanation

To find slant height $l$ use formula:

CS A = l \cdot r \cdot π

After substituting $CS A = 3513.9112 cm$ and $r = 20.2 cm$ we have:

3513.9112 cm = 20.2 cm \cdot l \cdot π

l = \frac{3513.9112 cm}{20.2 cm π}

l \approx 55.3718
