Answer: 18pi unit squared

Explanation:

Area of a circle = πr2

Radius of Circle G= 3units

Area of circle G= πr2

= π (3×3)

= 9π unit squared

Maria draws a circle with double the area of circle G. This will be:

2 × 9π

= 18π2

= 18pi unit squared

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.
