Remember the formula of the area of a circle is:
V =  \pi * r^{2}
SO given that
V = 226.98
and \pi = 3.14
Plug in a chug
226.98 = 3.14 * r^{2}
r^{2}=  72.287
r = 8.50

Remember that d = 2 * r
d = 2 * 8.5 = 17

I need help I don’t understand and I need to show my work who would help me??
stich3 [128]

Answer: b

Step-by-step explanation:

In the last question, you wrote on a second equation "13x ...." kkk

Let's go:

We have to check each one answer in the following system:

x - 2y = 7

3x + 7y = 8

I can use the substituition method to solve this system...

x = 7 + 2y

3x + 7y = 8

3(7 + 2y) + 7y = 8

21 + 6y + 7y = 8

13y = 8 - 21

13y = -13

y = -1

x = 7 + 2.(-1)

x = 5

Finally, the correct answer is the second one (letter b).

Rearrange each of the following in slope/y-intercept form, y = mx + b.
attashe74 [19]

Answer:

a.

{ \tt{3x - 6y + 8 = 0}} \\ { \tt{ 6y = 3x - 8}} \\ { \boxed{ \bf{y =  \frac{1}{2} x -  \frac{4}{3} }}}

b.

{ \tt{ - 2x - 5y - 2 = 0}} \\ { \tt{5y =  - 2x + 2}} \\ { \boxed{ \bf{y =   - \frac{ 2}{5} x +  \frac{2}{5} }}}

What is the value of f^-1(-3)?​
poizon [28]

Flip the curve over <em>y</em><em> </em><em>=</em><em> </em><em>x</em><em> </em>then observe what is y when x = -3. You will find that f^{-1}(x)=1.5.

Hope this helps.
