Answer:
94.2
Step-by-step explanation:
circumference is d(pi)
20(3.14) = 94.2
Answer:
The circumference of the circle is 62.8 mm.
Step-by-step explanation:
We must first know the formula for finding the circumference.
C = dπ
Let's plug in our diameter. We will use 3.14 for pi.
C = (20)(3.14)
Multiply the numbers together.
C = 62.8
So, the circumference of a circle with a diameter of 20 mm is 62.8 mm.
