First you have to find the area of the smaller inner circle:
A=<span>πr^2
A=</span><span>π4^2
A=</span><span>π16
A= 3.14 x 16
A= 50.24

Then, you have to find the area of the whole circle:
</span>A=πr^2
A=π6^2
A=π36
A= 3.14 x 36
A= 113.04
<span>
Now, you simply subtract 50.24 from 113.04 to get 62.8

Write the equation of a line that is perpendicular to y = -8 3 x + 4 and goes through the point (5, 2)
zhuklara [117]

Answer:

y = 3/8x + 1/8

Step-by-step explanation:

The slope of a perpendicular line is the opposite and reciprocal of the original slope.

-8/3 -> 3/8

Find the new y-intercept.

y = 3/8x + b

2 = 3/8(5) + b

2 = 1.875 + b

0.125 = b

y = 3/8x + 1/8

Best of Luck!

Help fast !!!! I need to get this done before I go to school ixl AA.1
Lorico [155]

Answer:

slope = - \frac{7}{5}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (0, - 7 ) ← 2 points on the line

m = \frac{-7-0}{0-(-5)} = \frac{-7}{0+5} = \frac{-7}{5} = - \frac{7}{5}
