Question

Find the diameter of a circle whose circumference is 18.85 m.

A. 12 m
B. 3.46 m
C. 6 m
D. 2.45 m

Answer 1

c=pi*d
18.85=3.14d
divide both sides by 3.14
x=6
answer is C.6m

Answer 2

The diameter of a circle is approximately 6 m

Step-by-step explanation-

Given that, the circle has the circumference as 18.85 m

From properties of geometry we know that,
`\text{Circumference of circle}=\pi * \text{Radius}`

Let us assume that the radius of the circle is x.

So, the circumference will be,

`\text{Circumference}=\pi * x`

But as it is given as 18.85m, so

`\Rightarrow \pi* x=18.85`

`\Rightarrow x=(18.85)/(\pi)=(18.85)/(3.141)=6.0012\approx 6\ m`
