Question

in circle g, r = 3 units. maria draws a circle with double the area of circle g. what is the area of marias circle? 6π units² 9π units² 12π units² 18π units²

Explanation:

Step1: Calculate area of circle G

The area formula of a circle is $A = \pi r^{2}$. For circle G with $r = 3$, $A_G=\pi\times3^{2}=9\pi$.

Step2: Find area of Maria's circle

Maria's circle has double the area of circle G. So $A_M = 2\times A_G=2\times9\pi = 18\pi$.

Answer:

$18\pi$ units$^{2}$
