Answer:
18*pi units squared.
Explanation:
The area of a circle can be calculated with the following formula:
Area = pi * r^2
Where r is the radius.
The circle G have a radius of 3 units, so its area is:
Area1 = pi * r^2 = pi * 3^2 = 9*pi
If the circle that Maria draws has double the area, so her circle have a area of:
Area2 = 2 * Area1 = 2*9*pi = 18*pi units squared.
