Question

The diameter of a circle is 4 cm. find it's area in terms of pi?!​

Answer 1

4
`\pi`

Explanation:

Radius is always half of the diameter.

So, 4/2=2

Now that we know the radius, we find the are.

The equation for area is
`\pi r^2`. When you insert everything, you get....

`\pi`
`*`
`2^(2)`

When you put it all together, we get... 4
`\pi`

Hope this helped :)

Answer 2

Explanation:

Radius of the circle = Diameter / 2 = 2cm.

Area = pi * (Radius)² = 4pi cm².
