Answer:
907.46
Step-by-step explanation:
We know the area of a circle is:

Answer: B = 9
Step-by-step explanation:
16-b=7
Rearrange so we can subtract 16 by 7
16 - 7 = 9
Substituting 9 for b and making sure it's correct.
16 - 9 = 7
To find the intercepts you sub the opposite value for 0
To find y:
<span>Y=4(0)+7
0*4=0+7=7
y=7
To find x:
0=4x+7
Subtract 7 from both sides
-7=4x
divide both sides by 4
x=-7/4
Final answer:
x-intercept: (-7/4,0)
y-intercept: (0,7) </span>
