Answer:
88 cm
Step-by-step explanation:
to find the circumference of a circle you can use the equation
d(pi)
d being diameter and pi in this case being 22/7
so you can directly multiply 28 and 22/7
28/1 * 22/7
you can cross cancel 28 and 7 making them 4 and 1 respectively
then you have 4/1 * 22/1
that is also 4 * 22
that is 88
