Question

If a circle has a radius of 4. then the area of the circle is

Answer 1

Answer

16
`\pi` or 50.24 units

Step-by-step explanation:

`\pi`
`r^(2)` and r is the radius, since we know what the radius is (r ) we can put this in to an expression

`\pi` · 4² = 16 units

If the answer is not 16 then its 50.24 units

Step-by-step explanation:

Now 16 is the correct answer but just in case I took this a step further.

If we estimate the area by using 3.14 which is (
`\pi` ) because sometimes that isn't natural to express the area using
`\pi`

I hope I helped you : )
