Question

AC is the diameter of the circle. Calculate the area of the sector in square units (to the nearest whole number) in square units created by CDB. picture attached

Answer 1

\(A_{sector} = \dfrac{n^{\circ}}{360^{\circ} } \pi r^2 \)

Where n is the degree measure of the central angle of the sector and of the arc, and r is the radius.
r = d/2
