Answer:
Please see attached picture for full solution.
First, we'll find the area of the large section, including the smaller section that is white.
Area of a circle: pi x r^2
A = pi x 7^2
A = 49pi x 120/360
A = 49/3 pi cm^2
Now, we'll find the area of the small section.
A = pi x 3^2
A = 9 pi x 120/360
A = 3pi cm^2
All that's left to do now is subtract.
49/3 pi - 3 pi
40/3 pi cm^2
(or 13 1/3 = 13.33 cm^2)
Hope this helps!
Yanira = Y
Tim = T
Hannah = H
-----------------
Therefore:
Y=T+3
Y=2H
T=H+2
---------------
Now, we know that:
Y=T+3
But we also know that:
T=H+2
Therefore:
Y=(H+2)+3
Y=H+5
-------------------
Now we can combine the equations:
Y=H+5
Y=2H
Therefore:
2H=H+5
2H-H=5
So, H=5.
---------------------
If H=5,
Y=2H=2*5=10
---------------------
If H=5,
T=H+2=5+2=7
-----------------------
