Find the circumference of the circle in terms of pi? [30]
2 answers:
Answer:
60π
Step-by-step explanation:
If the circle has radius of 30 units, substitute r=30 into the formula C = 2πr.
C = 2π(30)
C = 60π
To find the circumference of the circle shown here, let's start with writing the formula down.
Circumference = 2
r
We have to divide 60 by 2 because the radius is always half the diameter. Now, we can plug in 30 for r in the formula.
Now we have
circumference = 230.
This equals 60.
