Answer:87.92
Step-by-step explanation: you multiply the diameter by pie or 3.14 to get the circumference
C = 2 pi r
R is radius and it’s half of diameter
Pi is always a constant = 3.14
Diameter = D = 2r
We substitute the 2r with D
C = D pi = 28*3.14
Circumference = 87.9 cm (don’t forget your units)
R is radius and it’s half of diameter
Pi is always a constant = 3.14
Diameter = D = 2r
We substitute the 2r with D
C = D pi = 28*3.14
Circumference = 87.9 cm (don’t forget your units)
