Answer:
56.25π square inches
Explanation:
The area of a circle is calculated using the formula below:
[tex]A=\pi r^2[/tex]
First, determine the radius, r:
[tex]\text{Radius}=\frac{\text{Diameter}}{2}=\frac{15}{2}=7.5\; \text{inches}[/tex]
Substitute r=7.5 into the formula:
[tex]\begin{gathered} A=\pi\times7.5^2 \\ A=56.25\pi\text{ square inches (or }56\frac{1}{4}\pi\text{ square inches)} \end{gathered}[/tex]
