SAT Question e86f0651: Area and Volume answer and explanation with Desmos solution

Choice D is correct. The area, $A$, of a circle is given by the formula $A=\pi r^2$, where $r$ is the radius of the circle. It's given that the circle has a radius of $43$ meters. Substituting $43$ for $r$ in the formula $A=\pi r^2$ yields $A=\pi {\left(43\right)}^2$, or $A=1,849\pi$. Therefore, the area, in square meters, of the circle is $1,849\pi$.
