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
Answer:
You can draw a general triangle to start a proof unless you are given any specific qualities the triangle must have the triangle doesn't have to be draw to scale.
Step-by-step explanation:
<em>T= 250 + 45a.</em>
<em>Since the cost of the medicine costs $250, and there is $45 dollars per appointment then 45 a would represent the 45 dollars for every appointment she chooses to have.</em>

Answer:
198 km
Step-by-step explanation:
The speed of the boat supposed to be x km/h
(x+2)*9 = (x-2)*11
9x + 18 = 11x – 22
2x = 40
X = 20
Distance between 2 places: (20 + 2) * 9 = 198 km
Or (20 – 2 ) * 11 = 198 km
