Answer: C
Step-by-step explanation:
The area of the larger square is a^2 and the area of the smaller square is b^2, so the area is a^2 + b^2, not (a+b)^2.
No because being proportional only relates to multiplication not addition or subtraction.
Answer:
154 girls.
Step-by-step explanation:
If ratio of girls to boys is 3 : 4 then 3 / (3+4) = 3/7 of the total is girls.
Number of girls = 3/7 * 360
= 154.
C = pi * d
452.16 = 3.14 * d
Divide both sides by 3.14
144 = d
