Answer:
Around 31.42 in
Explanation:
Assuming you mean circumference of the circle and the diameter is 10.....
If the diameter is 10, then the radius is 5 because the radius is always half the diameter.
The formula for finding circumference 2(pi)r
r = radius = 5
So 2(pi)(5) = 10(pi) = ~31.42
Circumference is around 31.42 in
Hope this helps!
