a.) 56 in.

b.) 28 in.

c.) 88 in.

d.) 44 in.

Answer 1

so than given that the diameter of a circle is 28 inches so from this result the radius is d/2 = 28/2 = 14 inches

than the circumference of circle will be equal 2*3,14*14 = 6,28 *14 = 87,92 so rounded equal 88 in.

so this mean that choice c.) is right sure
