Question: If a circle has a radius of 5 cm, what is the circumference of the circle? (Use π ≈ 3.14)

Options:

Correct Answer: 31.4 cm

Solution:

The circumference of a circle is given by the formula C = 2πr. Thus, C = 2 * 3.14 * 5 = 31.4 cm.

If a circle has a radius of 5 cm, what is the circumference of the circle? (Use π ≈ 3.14)

If a circle has a radius of 5 cm, what is the circumference of the circle? (Use π ≈ 3.14)

Step 1: Identify the radius of the circle. In this case, the radius (r) is 5 cm.
Step 2: Recall the formula for the circumference (C) of a circle, which is C = 2πr.
Step 3: Substitute the value of π with 3.14 in the formula. So, it becomes C = 2 * 3.14 * r.
Step 4: Now, substitute the radius (r = 5 cm) into the formula. It becomes C = 2 * 3.14 * 5.
Step 5: Calculate the multiplication. First, calculate 2 * 3.14 = 6.28.
Step 6: Now multiply 6.28 by 5. So, 6.28 * 5 = 31.4.
Step 7: Therefore, the circumference of the circle is 31.4 cm.

Circumference of a Circle – The circumference is the distance around a circle, calculated using the formula C = 2πr, where r is the radius.
