Question

which statements are true regarding the area of circle d? select two options. the area of the circle depends on the square of the radius. the area of circle d is 36π cm². the area of circle d is 324π cm². the area of the circle depends on the square of pi. the area of the circle depends on the central angle.

Explanation:

Step1: Recall area formula

The formula for the area of a circle is $A = \pi r^{2}$, where $r$ is the radius. So the area depends on the square of the radius.

Step2: Calculate area

Given $r = 18$ cm, substitute into the formula: $A=\pi\times(18)^{2}=324\pi$ $cm^{2}$.

Answer:

The area of the circle depends on the square of the radius.
The area of circle D is $324\pi$ $cm^{2}$
