Question

what is the approximate area of the circle shown below? a. 24.5 cm² b. 191 cm² c. 49 cm² d. 96 cm²

Explanation:

Step1: Recall area formula

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

Step2: Identify radius

The radius $r = 7.8$ cm.

Step3: Calculate area

$A=\pi\times(7.8)^{2}\approx3.14\times60.84 = 191.0376\approx191$ cm².

Answer:

B. 191 cm²
