Question

Find area of sector GHJ. Round to the nearest hundredth.(Info in figure)

Answer 1

Given the central angle of the arc is angle GHJ which is equal to 60 degrees and the radius of the circle is 5 units.

Now, the area of the sector GHJ is obtained as follows:

`\begin{gathered} A=(60)/(360)*\pi r^2 \\ =(1)/(6)*(22)/(7)*5*5 \\ =13.09 \end{gathered}`

The area of the sector is 13.09 unit^2.
