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 :)

If y=(x+3) 2 then (-2x -6) 2 must equal

aleksandrvk [35]

y(x+3)2 then (-2x-6)2

is you have to distribute 2 like

2x+6=-4x-12

-2x -2x

6=-2x-12

+12 +12

-2x=0

x=0
