Transcribed Image Text:FINDING THE DIAMETER OR RADIUS
If we are given the circumference of a circle we can calculate its diameter and radius.
Example 3
| Self Tutor
What is the diameter of a circular pond with circumference 100 m?
Td = C
Td = 100
100
d =
{dividing both sides by 7}
dz 31.8
{100 E
}
So, the diameter is about 31.8 m.
