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 )
.
Let the value of radius be r.
Now, putting the formula of circumference to get the radius:
Circumference=
(putting the value of π = 3.14)
Dividing by 6.28 on both the sides:
Radius = 71.65cm
Therefore, the radius of the tabletop in cm is 72 cm (approximately).
