Question

The radius of a circle is

35
centimeters. Find the area of the circle. Use
22/7
​as an approximation for π.

Answer 1

`\textit{area of a circle}\\\\ A=\pi r^2 ~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=35 \end{cases}\implies A=\pi 35^2\implies A=\cfrac{22}{7}\cdot 35^2\implies A=3850`
