Answer 1

Diameter

There is a a circle whose circumference is 34.54 cm. Find the diameter of the circle. Remember use 3.14 for π.

- To know the diameter divide 34.54 cm by pi (π) to get the answer.

`\large \tt d = (34.54)/(\pi) \\ \large \tt d = 11cm`

Therefore, the diameter of the circle is 11cm

Answer 2

`\huge\boxed{Diameter=11cm}`

Explanation:

Important information:

Circumference of a circle=
`\pi*diameter`

Method:

To work out the diameter, we would need to divide the circumference of 34.54 by pi, which in this case is 3.14, this gives us 11cm. This is because we are simply rearanging the formula of the circumference of a circle to make the diameter the subject.

Step By Step:

1) Rearange the formula to make the diameter the subject.

`diameter=(circumference)/(\pi)`

2) Divide 34.54 by 3.14(
`\pi`).

`34.54/3.14=11cm`
