Question

Circle O has a circumference of approximately 28.3 cm.

Answer 1

Answer:

A) 4.5 cm

Step-by-step explanation:

Given: Circumference of the circle = 28.3 cm

Here we are asked to find the radius "r".

2.π.r = 28.3

The value of π = 3.14

2*3.14.r = 28.3

6.28r = 28.3

Dividing both sides by 6.28, we get

r = 28.3/6.28

r = 4.5 cm.

The radius of the circle r = 4.5 cm

Answer: A) 4.5 cm
