Answer:
ΔV = 865.51 mm^3
Step-by-step explanation:
In order to calculate the difference in volume between both baseballs you use the following formula for the volume of a sphere:
(1)
where r is the radius of he sphere.
You calculate the volume of each sphere:
First baseball:
radius = 23.2mm/2 = 11.61mm
![V_1=\frac{4}{3}\pi (11.61mm)^3=6555.18\ mm^3](https://tex.z-dn.net/?f=V_1%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%2811.61mm%29%5E3%3D6555.18%5C%20mm%5E3)
Second baseball:
radius = 24.2mm/2 = 12.1mm
![V_2=\frac{4}{3}\pi (12.10)^3=7420.70\ mm^3](https://tex.z-dn.net/?f=V_2%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20%2812.10%29%5E3%3D7420.70%5C%20mm%5E3)
Then, the difference in the volumen of both spheres is:
![\Delta V=V_2-V_1=7420\ mm^3-6555.18\ mm^3=865.51\ mm^3](https://tex.z-dn.net/?f=%5CDelta%20V%3DV_2-V_1%3D7420%5C%20mm%5E3-6555.18%5C%20mm%5E3%3D865.51%5C%20mm%5E3)
I am sure it would be 27 percent
Answer = 4
10^2 = 100
8^2 = 64
100 + 64 = 164
180 - 164 = 16
Square root of 16 = 4
