Answer: B

Step-by-step explanation: A=πr2

The formula for calculating the area of a circle is A = π​r​2 where pi (π) equals 3.14 and the radius (​r​) is half the diameter.

You must times 5 by 5 because of exponents and then times it by pie

5 times 5 = 25

25 times pie is 78.5

What is an equation of the line that passes through the point (8,-8)(8,−8) and is perpendicular to the line 4x-3y=184x−3y=18?
Kitty [74]

Answer:

The equation of the line is y = -\frac{3x}{4} - 2

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

y = mx + b

In which m is the slope and b is the y-intercept.

Perpendicular lines:

When two lines are perpendicular, the multiplication of their slopes is -1.

Perpendicular to the line 4x-3y=18

First, we place this line into the format, to find the slope:

4x - 3y = 18

3y = 4x - 18

y = \frac{4x}{3} - 6

This line has slope 4/3. So, for the perpendicular line, the slope will be of m as such:

\frac{4m}{3} = -1

4m = -3

m = -\frac{3}{4}

So the desired line will have an equation in the following format:

y = -\frac{3x}{4} + b

Passes through the point (8,-8)

We use this to find b. This point means that when x = 8, y = -8. So

y = -\frac{3x}{4} + b

-8 = -\frac{3*8}{4} + b

-8 = -6 + b

b = -2

So

y = -\frac{3x}{4} - 2
