Answer:

The remaining area of the circle is 196.06 cm².

Step-by-step explanation:

(area of circle) - (area of triangle) = remaining area of the circle

πr² - ½bh

3.14(8)² - ½(3)(4)

3.14(64) - ½(12)

202.06 - 6

= 196.06

Answer:

195.06 cm²

Step-by-step explanation:

First let's find the area of the circle

$\pi r^{2}$

$\pi *8*8$

$64\pi$

= 201.06 cm²

Now let's find the area of the triangle

$\frac{1}{2} *base*height$

$\frac{1}{2} *3*4$

= 6 cm²

Now let's find the area of the shaded region

$201.06-6=195.06\: cm^{2}$

Hope this helps you.

Let me know if you have any other questions :-)

Find the output for the graph y = -6x + 25 when the input value is 3. = y = [?]

avanturin [10]

Answer

$x=\frac{11}{3}$

Explanation

Based on the given conditions, formulate:: $y=3$

Substitute $y=3$ into $y=-6x+25$ :: $3=-6x+25$

Rearrange variables to the left side of the equation: $6x=25-3$

Calculate the sum or difference: $6x=22$

Divide both sides of the equation by the coefficient of variable: $x=\frac{22}{6}$

Cross out the common factor: $x=\frac{11}{3}$

Write the slope-intercept form of the equation of each line.

gregori [183]

Greetings!

Answer:

2y = x - 6

Step-by-step explanation:

First, we must find the slope of the current equation.

This is the number in front of the x.

Seeing as this is -2x, the slope of this line is -2

When finding the slope of a line perpendicular, you need to find the $\frac{-1}{slope}$

So, in this case it is:

$\frac{-1}{-2}$

The negatives cancel out which leave $\frac{1}{2}$

So the gradient is $\frac{1}{2}$

Now, to find the equation of a line, you need to use:

y - y1 = m(x - x1)

Where ya and x1 are the values in the coordinates (2 , -2)

So y1 = -2, x1 = 2, and m is a half. Plug these values in:

y - - 2 = $\frac{1}{2}(x - 2)$

We need to get rid of the half so we multiply the whole equation by 2:

2y - - 4 = (x - 2)

The minus and the negative turn into a positive:

2y + 4 = x - 2

And now simply move the +4 over to the other side, making it a negative:

2y = -2 - 4 + x

Simplify:

2y = x - 6

<h3>So the equation of the line is 2y = x - 6</h3>
