Question

What is the circumference of the following circle?

Use 3.14 for πpi and enter your answer as a decimal.

Answer 1

Answer:

C = 28.26cm

Explanation:

The formula for the circumference of a circle is:

C = πd

where C is the circumference and d is the diameter.

We are given that the diameter of the circle is 9 cm, so we can substitute this value into the formula:

C = πd = 3.14 × 9 cm = 28.26 cm

Therefore, the circumference of the circle is 28.26 cm (rounded to two decimal places).
