Question

In OC, BD is a diameter with length of 24cm andACB = 60°. Calculate the area of the sector.(In terms of pie)

Answer 1

From the image given,

The area of the sector is given by;

`\begin{gathered} A=(\theta)/(360)*\pi r^2 \\ A=(60)/(360)*\pi*12^2 \\ A=(8640\pi)/(360) \\ A=24\pi \end{gathered}`

Therefore, the area of the sector in terms of pie is

`24\pi cm^2`
