The document explains how to calculate the circumference of a circle using either the diameter or radius. It provides the formulas for circumference using diameter (C=π x d) or radius (C=π x r x 2). Examples are given to demonstrate using both formulas. Readers are then asked to complete practice problems calculating circumference based on given diameter or radius values.

1. Finding the Circumference of
The Circle

2. Mr. Kim planted dwarf santan
around her circular flower garden
which has a diameter of 8 meters.
How many meters did she plant with
dwarf santan?

3. Formula for finding the Circumference
C=𝝅 x d
Use this formula in
finding the
circumference of the
Circle if the given is
diameter

4. C=𝝅 x r x 2
Use this formula in finding
the circumference of the
Circle if the given is radius

5. Examples
1.r=7cm
2.d=15cm
3.r=4.5m
4.r=9.5m
5.d=5cm

6. Exercise: Find the circumference of
the circle with the following radius or
diameter.
1.r=11cm
2.d=2cm
3.d=16cm
4.r=3m
5.d=16.5m

7. Assignment: Complete the Table
Below:
CIRCLE RADIUS DIAMETER CIRCUMFERENCE
A 24 cm
B 40 cm
C 35 cm
D 34.5 m

8. Direction: Using 3.14 for , name
the circumference of a circle with…
1. d=12cm
2. d=5cm
3. r=1m
4. r=2.5m
5. d=3.5cm
