Find the area of a segment of a circle whose diameter is 16 cm and central angle measures 80 degrees

Question

anonymous · Answer

The formula to find the area of a sector is: pi*r^2*(×°/360°)

Pi=3.14
R= half the diameter= 8cm
X°= 80°
Plug these values into the formula 
3.14*8^2*(80/360)=44.7cm^2
