Question

question 9 of 10 what is the approximate area of the circle shown below? 23 cm a. 1662 cm² b. 6648 cm² c. 72 cm² d. 145 cm²

Explanation:

Step1: Recall area - formula for circle

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

Step2: Identify the radius

Given that the radius $r = 23\ cm$.

Step3: Calculate the area

Substitute $r = 23$ into the formula: $A=\pi\times(23)^{2}=\pi\times529$. Using $\pi\approx 3.14$, we have $A\approx3.14\times529 = 1661.06\approx1662\ cm^{2}$.

Answer:

A. $1662\ cm^{2}$
