Answer: 
Step-by-step explanation:
For this exercise it is important to remember that, by definition, the length of the minor arc can be calculated wih the following formula:
In this case , according to the data given in the exercise, you know that:
Therefore, susbtituting those values into the formula, you get that length of AB is the following:
Answer:
What is the question?
Step-by-step explanation:
1 over 117649 is equivalent to (7^3)^-2
The one is the same everywhere so we ignore it.
Choice B
To calculate the volume of a sphere you must use the formula
v=4/3pir^3
The radius (r) is half of the diameter
r=13.5
v=4/3pi13.5^3
v=10305.99
Therefore the volume of the sports ball is 10306cm^3 (to the nearest tenth)
