Question

If the radius of a circle equals 1.5 cm, find its circumference correct to three decimal places.

Answer 1

the circumference is 9.424

Explanation:

to find the circumference we need the diameter and to get the diameter from the radius you multiply by 2

1.5*2=3

now we multiply 3 by pi(3.14)

3*3.14=9.424

so 9.42 is your circumference
