150-40=110
110/2= 55.
Each pair of shoe costs $55
C = 2πr
C = 2(3.14)(2.5)
C = 15.7 = 16 cm is your answer.
282.6 m = πD
282.6 m = (3.14)D
282.6 m/3.14 = 3.14/3.14 x D
90 m = D
90 meters is the diameter.
hope this helps you!!!

Step-by-step explanation:
Answer:
The beach ball can hold 523.33 cubic inches of air
Step-by-step explanation:
Diameter of beach ball = 10 inches
Radius of beach ball =![\frac{10}{2}= 5 inches](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B2%7D%3D%205%20inches)
We are supposed to find How many cubic inches of air can the beach ball hold
Volume of sphere = ![\frac{4}{3} \pi r^3](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%20%5Cpi%20r%5E3)
Where r is the radius
So, volume of sphere = ![\frac{4}{3} \times 3.14 \times 5^3=523.333 in^3](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%20%5Ctimes%203.14%20%5Ctimes%205%5E3%3D523.333%20in%5E3)
Hence The beach ball can hold 523.33 cubic inches of air
If there are 40 boys, there are 32 girls.
formula:
5x8= 40 ( the boys )
4x8 = 32 ( the girls )
