Question

What is the approximate length in inches of the radius of the circle

Answer 1

Given

The area of the circle is 1200 square inches.

To find the radius of the circle.

Step-by-step explanation:

It is given that,

The area of the circle is 1200 square inches.

That implies,

`\begin{gathered} Area\text{ }of\text{ }the\text{ }circle=\pi r^2 \\ \pi r^2=1200 \\ r^2=(1200)/(\pi) \\ r^2=381.972 \\ r=√(381.972) \\ r=19.5 \\ r=20inches \end{gathered}`

Hence, the radius of the circle is 20 inches.
