The circumference of the circle is 144.4 yards
Step-by-step explanation:
The circumference of a circle is C = 2πr, where
- r is the radius of the circle
- π is a constant ratio between the circumference of the circle and its diameter and its value is approximately 3.14
∵ The radius of a circle is 23 yards
- Use the rule above to find its circumference
∵ C = 2πr
∴ C = 2π(23)
∵ π ≅ 3.14
∴ C = 2(3.14)(23)
∴ C = 144.44 yards
- Round it to the nearest tenth
∴ C = 144.4 yards
The circumference of the circle is 144.4 yards

The formula for area of a circle is r² x π.
Since we know the diameter, we can firstly divide by 2 to find our radius.
4/2 = 2
Now that we know the radius, we can substitute it in and square the value.
(2)² x π
(4) x π
Since we're finding the area in terms of pi, we won't multiply by pi, giving us the answer of 4π.
Therefore, the area of the circle is equal to 4π.

Answer:
A) About $195.00
Step-by-step explanation:
In a normal distribution, the interval (mean - 3*standard deviation, mean + 3*standard deviation) account for about 99.7% of the values. In this case mean + 3*standard deviation = $87.00 + 3*$36.00 = $195.00. So, it 's expected that this amount of money would be the largest individual customer bill.
