Question

this circular stage has a radius of 25 meters. which equation could be used to find the area of the stage in square meters? a. a = 25π b. a = 50π c. a = π·25² d. a = π·50²

Explanation:

Step1: Recall area - formula for a circle

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

Step2: Identify the radius value

Given that the radius $r = 25$ meters.

Step3: Substitute the radius into the formula

Substitute $r = 25$ into $A=\pi r^{2}$, we get $A=\pi\times25^{2}$.

Answer:

C. $A=\pi\cdot25^{2}$
