Question

Find the area of the shaded sector. Round your answer to the nearest hundredthBD = 18 cmBcE136D700.00

Answer 1

The area of a circular sector is given by:

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

In this case each shaded part has an angle of 136°, this means that the total circular sector has a total angle of 272°, plugging this value and the value of the radius into the equation above we have:

`A=(272)/(360)\pi(18)^2=769.06`

Therefore the area of the shaded region is 769.06 squared cm and the answer is C.
