A carpenter is making a tabletop with circumference 4.5m. What is the radius of the tabletop in cm?

Answer:The radius of the tabletop in cm is 72 cm (approximately).Step-by-step explanation:Given:Circumference of tabletop is 4.5m.So, to get the radius in cm.Now, we convert the unit of circumference from m to cm.( 1m = 100 cm )[tex]4.5m = 4.5\times 100cm[/tex]                [tex]= 450 cm[/tex].Let the value of radius be r. Now, putting the formula of circumference to get the radius:Circumference=[tex]2\pi r[/tex][tex]450 =[/tex][tex]2\times 3.14\times r[/tex] (putting the value of π = 3.14)[tex]450=[/tex][tex]6.28\times r[/tex]Dividing by 6.28 on both the sides:[tex]71.65=r[/tex]Radius = 71.65cmTherefore, the radius of the tabletop in cm is 72 cm (approximately).
