Step-by-step explanation:
area of larger circle = πr² = (3.14)(250²) = 196,250
area of smaller circle = πr² = (3.14)(200²) = 125,600
area of full donut = 196,250 - 125,600 = 70,650
20/360 = 1/18 of full donut
1/18(70,650) = 3925 units²

The 982 part seems wrong. Are you sure it isn't 981?
around 436 if I use 981 instead. 982 would give a decimal and that would be kinda weird for a part human.
Step-by-step explanation:
You can divide the 205 by 5 to simplify the ratio down. 205/5 = 41. Then you can multiply by 4 to find then number of boys.
981
So you can add the 5 and 4 together to 9 and then divide 981 by 9 to get 109. Then you can multiply by 4 to get 436.
Hope this helps!
