Question

Find the area of the circle. Use 22/7 for tt. Round your anwser to the nearest hundredth.

Answer 1

The formula for the area of circle is,

`A=(\pi)/(4)(d)^2`

Determine the area of circle for d = 49 cm.

`\begin{gathered} A=(\pi)/(4)\cdot(49) \\ =(22)/(7)\cdot(1)/(4)\cdot49\cdot49 \\ =1886.5 \end{gathered}`

So area of circle is 1886.5 cm^2.
