Question

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

Explanation:

Step1: Recall area formula

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

Step2: Identify radius value

The radius $r = 23$ cm.

Step3: Calculate the area

$A=\pi\times(23)^{2}=\pi\times529$. Taking $\pi\approx 3.14$, we have $A\approx3.14\times529 = 1661.06\approx1662$ $cm^{2}$.

Answer:

B. $1662$ $cm^{2}$
