1) Take the perimeter and divide it by 4.
2) Take the answer from step 1 and square it (multiply by itself)

It's simple. If you know the perimeter of a square, just divide by 4 due to the 4 sides making the perimeter up. Now you have the length of just one side. Area = l*w or in this case s^2, so just multiply the side by itself and you have the area of a square!

What is the radius of a circle in which a 30 degrees arc is 2 inches long

igomit [66]

arc length = pi /180 * angle in degree * radius

2 = pi/180 * 30 *r

2 = pi/6 *r

multiply by 6/pi

12/pi =r

3.819718634 =r

Answer: r =3.82 inches

On a coordinate plane, a line has points (negative 2, negative 4) and (4, 2). Point P is at (0, 4). Which points lie on the line

NikAS [45]

Answer:

the correct options are:

(–1, 3), (–2, 2) and (–5, –1)

Step-by-step explanation:

Given that a line passes through two points

A(-2, -4) and B(4, 2)

Another point P(0, 4)

To find:

Which points lie on the line that passes through P and is parallel to line AB ?

Solution:

First of all, let us the find the equation of the line which is parallel to AB and passes through point P.

Parallel lines have the same slope.

Slope of a line is given as:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$m=\dfrac{2-(-4)}{4-(-2)} = 1$

Now, using slope intercept form ( $y = mx+c$ ) of a line, we can write the equation of line parallel to AB:

$y =(1)x+c \Rightarrow y = x+c$

Now, putting the point P(0,4) to find c:

$4 = 0 +c \Rightarrow c = 4$

So, the equation is $\bold{y=x+4}$

So, the coordinates given in the options which have value of y coordinate equal to 4 greater than x coordinate will be true.

So, the correct options are:

(–1, 3), (–2, 2) and (–5, –1)
