Question

Find the area of this circle. Use 3 for a.A = 7r2=11 in[?] in?

Answer 1

We want to find the area of the circle in the picture given.

We have been given the formula as

`\begin{gathered} A=\pi r^2 \\ We\text{ are told to take }\pi\text{ as 3} \\ \end{gathered}`

From the circle, the radius r = 11 in.

The area of the circle becomes

`\begin{gathered} A=\pi r^2 \\ A=\pi* r^2 \\ A=3*11^2 \\ A=3*11*11 \\ A=363in^2 \end{gathered}`

Hence the answer is 363 square-inches
