∙ 13y agoThe total central angle of the whole circle is 360 degrees.
When the circle is divided into 20 equal sectors, each sector has
a central angle of
(360/20) = 18 degrees.
The diameter of the circle is irrelevant. The answer is the same
for diameters of 20 millimeters or 20 miles.

What is the area of a sector with a central angle of 130 degrees and a diameter of 9.9 cm?
Sectors don't have diameter, only radius. However... Assuming the the circle has a diameter of 9.9 then the area of the circle is 4.95 x 4.95 x 3.14 which is 76.93785 cm2. As the sector has a central angle of 130o then its area is 130/360 of the above figure ie 27.28 cm2 to two decimal places.
