Question

A circle has a circumference of 1{,}133.541,133.541, comma, 133, point, 54 units.
What is the diameter of the circle?

Answer 1

Step-by-step explanation:

circumference of a circle= 2 pi r

1,133.541=2*22/7*r

r=180.31

d= 2*180.31

= 360.62

Answer 2

Given:

The circumference of a circle = 1,133.541 units

Let the radius of circle = r

We have to find, the diameter of the circle (d).

Solution:

We know that,

The circumference of a circle = 2πr

⇒ The circumference of a circle = π(2r)

⇒ The circumference of a circle = πd [ ∵ d = 2r]

∴ 3.14 × d =  1,133.541

⇒ d = \dfrac{ 1,133.541}{3.14} units

⇒ d = 361 units

∴ The diameter of the circle (d) = 361 units

Thus, the diameter of the circle (d) is equal to "361 units".
