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 = 71.65cm
Therefore, the radius of the tabletop in cm is 72 cm (approximately).
