Answer:
Step-by-step explanation:
Area of the specified region = Area of larger circle - Area of smaller circle
Larger circle:
r = 16 + 3 = 19 m
Area = πr²
=π * 19 * 19
= 361π m²
Smaller circle:
r = 16 m
Area = πr²
=π * 16 * 16
= 256π m²
Area of the specified region = 361π - 256π = 105π m²
Are you serious? oh well..
ok, draw a circle. devide the circle into 5 parts. color in 3 of the parts.
Now, draw 4 more of these.
Now, count the pieces.
For every 7 boys, there is one girl
So: 63/7 = 9
There are 9 girls.
