What is the difference in the area of a circle with diameter 4m and a circle with diameter 6m?
nordsb [41]

Answer:

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

Step-by-step 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 :)
