Acircle has a radius of 6 ft.

what is the area of the sector formed by a central angle measuring 5π/3 ?

use 3.14 for pi.

enter your answer as a decima

(5 / 3) * PI = 300 degrees
Sector area = (central angle (degrees) / 360) * PI * radius^2
Sector area = (300 / 360) * 3.14 * 36
Sector area = (5/6) * 3.14 * 36
Sector area = 30 * 3.14
Sector area = 94.2 square feet
