So, imagine the trainer is in the very middle of the circle and he is holding out a rope that's attached to the horse. The rope here from the trainer to the horse represents the radius of the circle. The horse trots around the trainer (middle point) in a circle.
The formula to find area of a circle is A = pi*r^2 (pi times r squared where r is radius)
We know that the radius of the "circle" here formed as the horse trots around the trainer is 31 (the 31 foot long rope).
So let r = 31 & plug the value into the formula to find circle area.
A = pi*31^2 = 3019.07054
The area is therefore 3019.07 square feet. (rounded)
Answer:
The probability of a event is a number between 0 and 1 or 1 and 10 or 1 and 100.
Step-by-step explanation:
The correct answer is - The probability of a event is a number between 0 and 1 or 1 and 10 or 1 and 100.
Reason -
Probability - It is a number between 0 and 1
Sample space - All the possible outcomes of an experiment.
Outcome - One of the individual results that can occur in an experiment.
Event: A subset of the sample space
Compound event : A event with more than one outcome.
Answer:
Part 1) The area of the circle is 
Part 2) The circumference of the circle is 
Step-by-step explanation:
step 1
The area of a circle is equal to
we have
---> the radius is half the diameter
substitute
step 2
The circumference of a circle is equal to
we have
substitute
LCD would be 18
8/9 = 16/18
2/3 = 12/18
1/9 = 2/18
Just wondering, Is there options?
