Question: A circle has a radius of 2.5 m. What is its circumference?

Options:

Correct Answer: 15.7 m

Solution:

Circumference = 2πr = 2π(2.5) = 5π ≈ 15.7 m.

A circle has a radius of 2.5 m. What is its circumference?

A circle has a radius of 2.5 m. What is its circumference?

Step 1: Understand that the circumference of a circle is calculated using the formula: Circumference = 2πr, where r is the radius.
Step 2: Identify the radius of the circle, which is given as 2.5 meters.
Step 3: Substitute the radius into the formula: Circumference = 2π(2.5).
Step 4: Calculate 2 times 2.5, which equals 5.
Step 5: Now, the formula looks like this: Circumference = 5π.
Step 6: To find an approximate value, multiply 5 by the approximate value of π (which is about 3.14).
Step 7: Calculate 5 × 3.14, which equals approximately 15.7 meters.

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