Question: In a circle, if the diameter is 14 cm, what is the circumference of the circle?

Options:

Correct Answer: 43.96 cm

Solution:

The circumference of a circle is given by C = πd. Thus, C = π(14) ≈ 43.96 cm.

In a circle, if the diameter is 14 cm, what is the circumference of the circle?

In a circle, if the diameter is 14 cm, what is the circumference of the circle?

Step 1: Understand that the diameter of the circle is given as 14 cm.
Step 2: Recall the formula for the circumference of a circle, which is C = πd, where d is the diameter.
Step 3: Substitute the diameter into the formula: C = π(14).
Step 4: Use the approximate value of π, which is about 3.14, to calculate the circumference: C ≈ 3.14 × 14.
Step 5: Perform the multiplication: 3.14 × 14 = 43.96.
Step 6: Conclude that the circumference of the circle is approximately 43.96 cm.

Circumference of a Circle – The circumference is the distance around the circle, calculated using the formula C = πd, where d is the diameter.
