Answer:
28.3 (b)
Step-by-step explanation:
To solve circumference, you will need to use the equation C = 2 *pi* r
for this, we will use 3.14 for pi and the radius is 4.5 so this is how we need to solve it
C= 2 pi (4.5) Solve 2*4.5
C= 9 pi Now we input 3.14 for pi and multiply
C= 9(3.14)
C= 28.26 Now we round to the nearest tenth to get
C=28.3
For the girls:
12:30
Simplifying it, we get:
6: 15
2: 5
For the boys:
16:40
Simplifying it, we get:
8:20
4:10
2:5
So yes, the ratios are both the same for boys and girls.
180 divided by 5 = 36..................
