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
Thank you.
The approximate length of the radius for a circle with circumference of approximately 28.3 cm is 4.5 cm.
An equation is an expression that shows the relationship between two or more numbers and variables.
Let r represent the radius of the circle, hence:
Circumference = 2πr
Substituting:
28.3 = 2π(r)
r = 4.5 cm
The approximate length of the radius for a circle with circumference of approximately 28.3 cm is 4.5 cm.
