Question

The circumference of a circle is 4.8m. Calculate the area of the circle​

Answer 1

1.83 (approximate)

Explanation:

First, we need to find the radius of the circle.

Using the formula:

`C=2 \pi r`

We have to reorganize terms:

`r=(C)/(2\pi)`

`(4.8)/(2 * \pi)`

r ≈ 0.76

Now we have the radius and the circumference in order to find the area.

Use the formulas:

`A= \pi r^2`

`C=2 \pi r`

A = C^2/4
`\pi` = 4.8^2 / 4 * pi = 1.83

Answer 2

A≈1.83m²

Explanation:

Using the formulas

A=πr2C=2πr

Solving forAA=C24π=4.824·π≈1.83346m²
