Answer: 9.3cm

Step-by-step explanation:

Given: The lateral area of the cone =574 cm^2

The radius of the cone = 19.6 cm

We know that the lateral surface area of the cone is given by ;-

LA=\pi r l, where r is the radius and l is the slant height of the cone.

\\\\\Rightarrow\ 574=\pi (19.6)l\\\\\Rightarrow\ l=\dfrac{574}{\pi\times19.6}\approx9.3\ cm

Hence, the slant height of the cone = 9.3 cm

DedPeter [7]
For the answer to the question above, 
a1 = 40 
<span>a2 = 20 </span>
<span>a3 = 10 </span>
<span>.. </span>
<span>aN = (1/2^N-1) a1 { in general aN= (r^N-1) A1 </span>

<span>a5 = (1/2^4) 40 = 40/16 = 2.5
