Question

question 1 of 10 what is the approximate area of the circle shown below? 4.2 in a. 55.4 in² b. 26.4 in² c. 13.2 in² d. 222 in²

Explanation:

Step1: Recall area formula

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

Step2: Substitute radius value

Given $r = 4.2$ in, so $A=\pi\times(4.2)^{2}$.

Step3: Calculate the result

$A=\pi\times17.64\approx3.14\times17.64 = 55.3896\approx55.4$ in$^{2}$.

Answer:

A. $55.4$ in$^{2}$
