in order to evaluate this question , we will first of all find the radius using the formula for finding the circumference of a circle , we will then find the area of a circle.

<u>solution</u>

given that circumference of a circle = 3/2picm

recall that the formula for finding the circumference of a circle = 2πr

3/2picm = 2πr

multiply through by 2

3picm = 4pir

divide both side by 4pi

3pi cm/4pi = r

r = 3/4 picm

Recall that the Area of a circle = πr²

Area = pi ( 3/4)² cm

Area = 9/16pi cm²

What is the equation of the line that is perpendicular to the given line and has an x-intercept of 6?

zhenek [66]

First we have to find the slope of the givent line and for that we use rise / run method .

The points are (-4,4),(4,-2)

Here rise is

$-2-4 =-6$

And run is

$4-(-4)=8$

So slope is

$= \frac{-6}{8} = \frac{-3}{4}$

And the slopes of perpendicular lines are negative reciprocal of each other .

Therefore the slope of the required perpendicular line is

$-(- \frac{4}{3}) = \frac{4}{3}$

Now we use slope intercept form, and put x intercept , that is (6,0) and the slope that is 4/3 ,

$y=mx+b
\\
0 = \frac{4}{3}*6 +b
\\
0=8+b
\\
b =-8$

Therefore required equation is

$y= \frac{4}{3}x -8$

Correct option is the third option .

How many ways are there to travel in xyz space from the origin (0, 0, 0) to the point (4, 3, 5) by taking steps one unit in the

Virty [35]

I would think you would have to walk the 4 spaces out on the X axis. I would then turn and walk 5 spaces on the Z axis before turning up to walk the last 3 steps on the Y axis.

I think any other way would cause you to move in a negative direction. I hope this helps.
