4.72 x 1 = 4.72
8 x X =8x
We need to let the X alone so
4.72 divided 8 = 0.59
1 battery = 0.59

Y equals 8 X equals 575 Solve for slope intercept y equals mx + b

zhannawk [14.2K]

y = 8

x = 575

We want to solve for b in the slope-intercept form y = mx + b.

To complete this problem, we need the value of m, the slope. If you know m, then just plug into y = mx + b this way:

8 = 575m + b

Answer:

option D . 254.34cm^2

Step-by-step explanation:

The picture of the question in the attached figure

The options are:

A . 56.52cm^2

B . 141.30cm^2

C . 1,017.36cm^2

D . 254.34cm^2

step 1

Find the diameter of the largest circle

we know that

The diameter of the largest circle is equal to the sum of the diameter of the two inside circles

$D=6+12=18\ cm$

step 2

Find the area of the largest circle

we know that

The area of the circle is given by the formula

$A=\pi r^2$

we have

$r=18/2=9\ cm$ ----> the radius is half the diameter

assume

$\pi=3.14$

substitute

$A=(3.14)(9^2)=254.34\ cm^2$
