Answer:

40cm

Step-by-step explanation:

If you are converting 40cm to one inch and the conversion ratio is 2.54 : 1, you would place 40 in the numerator as the original ration has 2.54/1 as a fraction and the same will apply to 40cm.

** This applies if you are finding which number is in the numerator and not the answer to how much 40cm in inches is.

The formula to calculate the lateral area of a cone is given by

$LA=pi*r*l$

where

LA=10.5pi in2

r=2.1 in

l=? slant height

substitute given values

$\begin{gathered} 10.5pi=pi*2.1*l \\ solve\text{ for l} \\ l=\frac{10.5pi}{pi*2.1} \\ \\ l=5\text{ in} \end{gathered}$ <h2>The answer is 5 inches</h2>
