The radius is 4.9 and the Circumference is 9.8π
Step-by-step explanation:
Data:
Diameter = 9.8
Circumference = ?
Radius = ?
Radius
Radius is half of the diameter so radius = [tex]\frac{diameter}{2}[/tex]
Radius = [tex]\frac{9.8}{2}[/tex]
Radius = 4.9
Circumference
Circumference = 2πr
Circumference = 2π(4.9)
Circumference = 9.8π
Therefore, the radius is 4.9 and the Circumference is 9.8π
