Okay, so the volume of a sphere is 4/3 x pi x r^3.
The diameter of the sphere is 2.5, so the radius is 1.25cm. This cubed is 1.953125.
Multiply that by 3.14 to get 6.1328125. And finally, multiply by 4/3 to get 8.1770. To the nearest hundredth, we get that the volume of the sphere is 8.18cm^3.
Hope this helps:)
First u have to find the area 11x3=33, 3x1=3, 3x2=6 sum=42
You would set it up: .5/100 = x/490 and then cross multiply .5 time 490 and 100 times x, and end up with: 245=100x. divide by 100, and get 2.45
