Question

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

Answer 1

Answer-

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,$\text{Circumference of circle}=\pi \times \text{Radius}$

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

So, the circumference will be,

$\text{Circumference}=\pi \times x$

But as it is given as 18.85m, so

$\Rightarrow \pi\times x=18.85$

$\Rightarrow x=\dfrac{18.85}{\pi}=\dfrac{18.85}{3.141}=6.0012\approx 6\ m$

Answer 2

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