For number 1, add the sides of the triangle. They are all given. The answer is 19.
For number 2, you use the formula for circumference, 2 times pi times radius. The answer is 43.96.
For number 3, I assume that 5 is half of one side. You would double 5 to get ten and multiply it by four, since there are four sides in a square. The answer is 40.
For number 4, you would multiply 5 times pi, but don't solve it. ( since the directions are to leave the answer in terms of pi) The answer is 5 pi.
For number 5, add all the sides together like number 1. The answer is 18.
8 the answer is 8, you multiply 8 by its self
Answer:
22.3333333
Step-by-step explanation:
Mean = the sum of all of the numbers divided by the amount of numbers given. The sum (134) was divided by the number of numbers (6) to get 22.3333333. This is not 22 and 3 repeating, since my calculator would've rounded the last digit to 4.
