Question

What is the difference in the area of a circle with diameter 4m and a circle with diameter 6m?

Answer 1

The difference between the area of the two circles is 15.7m

Explanation:

I swear these be helping me with the CIEs coming up in May xD

Okay so the formula for a circle is
`\pi r^2`

The diameter is the double of the radius so

Cirlce A has a diameter of 4m so a radius of 2m

`\pi 2^(2)`

`\pi4`

`12.57m`

Circle B has a diameter of 6m so a radius of 3m

`\pi 3^2`

`\pi 9`

`28.27m`

To find the difference subtract 12.57 from 28.27

`28.27-12.57\\=15.7`

The difference between the area of the two circles is 15.7m

Hope this helps, if you still need help just comment :)
