The formula for calculating the area of the circle made by Sara is given by the following general formula:


A=\pi* r^2

where r = radius of the circle, and:


\text{radius}=\frac{\text{diameter}}{2}

Now, given that the diameter of the circle made by sara is 8 inches, the radius will be:


\begin{gathered} \text{radius}=\frac{\text{diameter}}{2} \\ \text{radius}=(8)/(2)=4\text{ inches} \end{gathered}

Now, the area of the circle will be:


\begin{gathered} A=\pi* r^2 \\ \text{Given that: }\pi=3.14,\text{ and r = 4 inches, we have:} \\ A=3.14*4^2 \\ A=3.14*16=50.24in^2 \end{gathered}

Therefore the area of the circle made by Sara is 50.24 square inches

Correct answer: Option A
