Question

Review: Solve for Area AND Circumference. A giant holiday cookie has a radius of 5 inches. What is the area of the cookie? What is the circumference of the cookie?

Answer 1

Remember that the formual for the area of a circle is:

`A=\pi r^2`

And the formula for the circumference is:

`C=2\pi r`

Using this formulas and the data given,

`\begin{gathered} A=\pi(5^2)\Rightarrow A=78.54 \\ C=2\pi(5)\Rightarrow A=31.42 \end{gathered}`

The cookie has an area of 78.54 square inches and a circumference of 31.42 inches
