Question

A circle has a circumference of 28.36 units what is the diameter of the circle

Answer 1

Answer:

The diameter of circle d is 9.03

Step-by-step explanation:

Circumference of Circle = 28.36

We need to find the diameter of circle.

The formula used to find the circumference of circle is:

C = 2πr

we know that radius is half of diameter

so r = d/2

Putting value of r in above equation

C = 2π(d/2)

C = πd

The value of π is 3.14. finding value of d

28.36 = 3.14 * d

=> d = 28.36 / 3.14

d = 9.03

So, the diameter of circle d is 9.03

Answer 2

Answer:

The diameter is approximately 9 units

Step-by-step explanation:

Circumference is given by

C = pi *d

28.36 = pi *d

Let use 3.14 for pi

28.36 = 3.14 *d

Divide each side by 3.14

28.36 /3.14 = 3.14 d/3.14

9.031847134 = d

The diameter is approximately 9 units
