Question

Find the area of each sector. round to the hundredths place

Answer 1

Given data:

The given radius is PQ=r=2.8 in.

The expression for the area of the shaded region is,

`\begin{gathered} A=((360^(\circ)-311^(\circ)))/(360^(\circ))\pi(r)^2 \\ =((360^(\circ)-311^(\circ)))/(360^(\circ))\pi(2.8)^2 \\ =3.35in^2 \end{gathered}`

Thus, the area of the shaded region is 3.35 sq-inches.
