A circle has a radius of 2 yards and a central angle AOB that measures 145 degree. What is the area of sector AOB? Use 3.14 for pi and round your answer to the nearest tenth.
A. 12.6 yd^2
B. 10.1 yd^2
C. 5.1 yd^2
D. 2.5 yd^2
area of secter = central angle*pai*r^2
= 145 * 3.14 * 2^2 ft^2
= (145 * 3.14 * 2^2)/(12*12) yd^2
= 12.6 yd^2
