Question

What is the area of the sector of the circle below, if the radius is 11 cm and the central angle < AOB measures 29 °. (round answer to the nearest tenth)

Answer 1

The area of the red sector is given by:

`\pi\cdot r^2\cdot((\angle AOB))/(360\degree)=\pi\cdot11^2\cdot(29\degree)/(360\degree)\approx30.6\text{ cm}^2`
