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
