The formula for the circumference of a circle is C = πd, where d is the diameter of the circle.
Substituting the given value of d=20 into the formula gives:
C = 3.14 x 20
C = 62.8
Rounding to the 10th decimal place, the approximate circumference is 62.8 units.
what is the approximate circumference of a circle that has a diameter of 20 use 3.14 for pi and express your answer to the 10th place
