Question

Find the area of each sector. Leave in terms of pi

Answer 1

choice B

Explanation:

using the formula:

`theta / 360\pi * r ^(2)`

Answer 2

B

Explanation:

Formula

`\textsf{Area of a sector of a circle}=\left((\theta)/(360^(\circ))\right) \pi r^2`

Solution

Given:

• 
  `r` = 9 cm
• 
  `\theta` = 60°

`\begin{aligned}\implies \textsf{Area} & =\left((60^(\circ))/(360^(\circ))\right) \pi \cdot 9^2\\\\ & = \frac16 \cdot \pi \cdot81\\\\ & = (81)/(6) \pi\\\\ & = (27)/(2) \pi \: \sf cm^2\end{aligned}`
