the question is based on the following circle graph. the graph represents the results of a survey in which 400 people were asked to identify the tv channel on which they preferred to watch the evening news.
wkod 13%
wanr 22%
wclm 24%
wwcn 41%
write a ratio to express the number of people who preferred wanr to those who preferred wclm
a. 11 : 12
b. 23 : 100
c. 46 : 100
d. 3 : 50

Option A is right

Step-by-step explanation:

The graph represents the results of a survey where 400 people were asked to identify the preferred TV channcel.

Of those the data collected gave

WKOD 13%

WANR 22%

WCLM 24%

WWCN 41%

Ratio of people who preferred WANR to those who preferred WCLM

= 22%/24%

=11:12

Hence answer is 11:12

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
