Answer:

Slant Height = 20.1 km
Radius = 9 km
Lateral Area = 568.3 km²

Step-by-step explanation:

The slant height is read from the diagram as 20.1 km.

The radius is half the diameter, so is 9.0 km.

The lateral area is ...

A = πrs = π(9.0 km)(20.1 km) ≈ 568.3 km²

Desmos uses r for a special purpose, so we have used r₁ to signify the radius of the cone. The "round" function works only to round to an integer, so special effort must be used to get rounding to 1 decimal place.
