Answer:

A = 82.53 in²

Step-by-step explanation:

We use the circumference equation C = 2πr and the area equation A = πr².

Using the first equation and the given circumference (32 in), we find the radius of the circle, and then use this result to find the area of the circle.

         

                                         C                            32 in

C = 2πr becomes r = ----------- and here r = ---------- = 5.10 in

                                        2π                            6.28

Then the area of the circle is A = πr², which here is A = 3.14(5.10 in)², which, when rounded off to two decimal places, is A = 82.53 in²

Consider the two number sets. Which set has the higher mean and what is that mean?
Otrada [13]

The mean is where you add all of the numbers in that set together, and divide it by the amount of numbers you have. E.g. For Set 1 - 10 + 15 + 20 + 25 + 30 + 50 = 150 ÷ 6 = 25

For Set 2 you just repeat the process:

1. Add the numbers in the set together, this gives you a total of 111

2. Then divide 111 by 5 as you have 5 numbers, giving you 22.2

Therefore set 1 has the higher mean :)

The answer is C, set 1, 25 :)
