Ответ:
62.8 inches
Step-by-step explanation:
The circumference of a circle can be found using:
c=π *d
We know that the diameter is 20 inches and we are using 3.14 for pi. We can substitute 20 in for d and 3.14 for pi.
c=3.14*20
Multiply 3.14 and 20
c=62.8
Add appropriate units: inches
c=62.8 inches
The circumference of the circle is about 62.8 inches
Ответ:
