Circumference Formula: C = πd
- <em>C</em> is circumference
- <em>d</em> is diameter
Step-by-step explanation:
<u>Step 1: Define</u>
Diameter <em>d</em> = 28 mm
<u>Step 2: Solve</u>
- Substitute in variables [Circumference Formula]: C = 3.14(28 mm)
- [Circumference] Multiply: C = 87.92 mm
Answer:

Step-by-step explanation:
The formula for the circumference of a circle with the diameter is:

Since the diameter is 3m, solve for
:

Answer:
102°
Step-by-step explanation:
that's the answer because 40+ 38 = 78. then 180- 78 = 102. Remember that in tringles, all three angles should add up to 180°
Answer: The mean of the data set is 25.
Step-by-step explanation:
To calculate the mean of a data set, first add up all the values.
17 + 34 + 19 + 27 + 30 + 23 = 150
Then divide the sum by the amount of values in the data set. Our sum here is 150 and the amount of data values is 6.
150 ÷ 6 = 25
