Given
The area of the circle is 1200 square inches.
To find the radius of the circle.
Explanation:
It is given that,
The area of the circle is 1200 square inches.
That implies,
[tex]\begin{gathered} Area\text{ }of\text{ }the\text{ }circle=\pi r^2 \\ \pi r^2=1200 \\ r^2=\frac{1200}{\pi} \\ r^2=381.972 \\ r=\sqrt{381.972} \\ r=19.5 \\ r=20inches \end{gathered}[/tex]Hence, the radius of the circle is 20 inches.
