Answer 2

Calculation of the Diameter of a Circle

To find the diameter of a circle when the circumference is given, we can use the formula:

Diameter = Circumference / π

Given that the circumference of the circle is 15.7 cm, we can calculate the diameter by dividing the circumference by π (pi). Let's perform the calculation:

Diameter = 15.7 cm / π

To ensure accuracy, let's round the value of π to the hundredths place.

Now, let's calculate the diameter using the rounded value of π:

Diameter = 15.7 cm / 3.14

Performing the calculation:

Diameter = 4.99 cm

Therefore, the diameter of the circle, rounded to the hundredths place, is approximately 4.99 cm.

Please note that the value of π used in this calculation is rounded for simplicity. The actual value of π is an irrational number and is approximately equal to 3.14159.
