Question

AC is the diameter. Calculate the area of the sector (to the nearest whole number) created by ∠CDB.

Any help would be awesome thanks :-)

Answer 1

Area of the circle is πr² which corresponds to an angle of 360° subtended at the center. Thus, the area of a sector subtending angle
`\theta` at the centre is:

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

In this case put $\theta$ equal to 30°
