Question

Finding π (optional)
You need:
• Six or fewer objects that have a round surface
• Yard or meter stick
• Ruler
• String (must be long enough to go around each of the round surfaces)
Directions:
1. List each object in the chart below.
2. Take your string and measure the distance around the circular object. Write that measurement
in the chart under Circumference.
3. Use your ruler to measure the diameter of the circular object. Write that measurement in the
chart under Diameter.
4. Divide the circumference by the diameter. Write that answer in the chart under Ratio. Was your
answer close to π

Answer 1

The circumference of the ball will be 43.988cm and dividing the circumference by the diameter equals pie.

How to calculate the circumference?

The object that's chosen in this scenario is a circular ball. The diameter of the ball is 14cm.

The circumference of the ball will be:

= 2πr

= 2 × 3.142 ×(14/2)

= 2 × 3.142 × 7

= 43.988cm

Dividing the circumference by the diameter will be:

= 43.988cm/14cm

= 3.142

The answer is close to pi.
