Answer:
77.283km^(2)

Explanation:

The formula for the lateral area of a cone
L.A is:


L.A=\pi r h

Where:


r=10km is the radius of the circular base of the cone

As we know its diameter
d=20km, its radius is
r=(d)/(2)=10km


h=2.46km is the height of the cone


L.A=\pi (10km)(2.46km)


L.A=77.283km^(2) This is the lateral area of the volcano with the shape of a cone
