Question

5) The radius of a circle is 6mm. If the sector area is 14.14 mm2, what is the degree measure of the sector?

Answer 1

Explanation:

sector area = angle/360 * pi * r^2

14.14 = angle/360 * 22/7 * 6^2

14.14 = angle/360 * 22/7 * 36

(360 * 14.14 * 7)/(22 * 36) = angle

angle = 44.99 = 45 degrees
