Answer:
a) If the diameter is 400 feet wide, then the radius is half that, which is 200 feet wide.
b) The circumfernce is π times the diameter, which is 400 feet. 400×π≈1256.64
c) She is not correct. She squared 400, which is 160000, when she should have squared 200, which is 40000. Then, multiply by π.
40000 × π ≈ 125663.7
You have to use the y=mx+b formula to find the equation
Dividing the 2 numbers I get 7.3 x 10^-6
The ratio of boys to girls would be
since you can divide both 14 and 21 by 7, the simplified form would be
.
The answer is 2 to 3.
