Answer: R=2.75
Step-by-step explanation: How to find the radius of a sphere?
This question seems very easy at first. You only have to find the center of the sphere and measure the distance to any point on its surface. However, how can you find this center in real, physical sphere, especially when it's closed? Let's look on a two of my suggestions:
Find the diameter. You can use two parallel planes and put the sphere between them. The distance between those plates equals the diameter of a sphere.
Find the volume. Prepare a graduated cylindrical container filled with water. Put a sphere into this cylinder, then bring out the sphere and measure the volume of displaced water
Each book costs $15. 90 divided by 6 is 15 which is also 90 over 6.
The awnser would be letter A because scatter plots don't go side ways or go up or downs and also scatter plots don't have any plots that go under it.<span />
