What is the ratio of the sector area to the area of the entire circle? answer is: 1/5

1/5

Step-by-step explanation:

Area of the sector = pi r^2 ( 72/360)

area of the circle = pi * r^2

divide these

Area of the sector = pi r^2 ( 72/360)

area of the circle = pi * r^2

cancel the pi and the r^2

Area of the sector   ( 72/360)

=

area of the circle  

divide the top and bottom of the fraction by 72

Area of the sector    

= 1/5

area of the circle
