Question

What is the approximate area of the shaded sector in the circle shown below?O A. 5.76 cm211 cmB. 31.7 cm230"O C. 2.88 cmO D. 126.7 cm

Answer 1

We will use the formular below:

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

where A is the area of the sector

r is the radius

Theta is the angle

θ=30 r= 11 π=22/7

substitute the values in the formula and evaluate

`A=(30)/(360)*(22)/(7)*11^2`

`A\approx31.7cm^2`
