I learned this recently and its a piece of pie! XD

Pi=3.14 or 22/7.

Radius- a straight line from the center to the circumference of a circle or sphere.

I'll hand you over a formula for this and you can plug the numbers in!

Radius= Diameter/2

Area= Pi x (Radius to the 2nd power)

Diameter= 2 x Radius

I hope this helps in some way!

Hello there!

First of all, find the slope of the right side of the graph. The slope is 2. So far we have:
y=2

Now look at the x coordinate of the point. Now we have:
y=2|x-0|
y=2|x|

Next the graph is shifted down 2 so add a negative two.
y=2|x|-2

I hope this helps!
Best wishes.

There is a line whose slope is 7 and whose y-intercept is -5. why is it's equation in slope-intercept form?​
Troyanec [42]

Answer:

y = 7x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 7 and c = - 5, then

y = 7x - 5 ← equation of line

Answer:

1. Quadrant 2

2. Quadrant 3

Step-by-step explanation:

The quadrants are ordered in a 'c' pattern. The first quadrant has coordinates (x,y). The second quadrant has coordinates (-x,y). The third quadrant has coordinates (-x,-y). The fourth quadrant has coordinates (x,-y).

The diameter of the base of the cone measures 8 units. The height measure 6 units. What is the volume of the cone?
ivolga24 [154]

Answer:

The  volume of the cone is  100.48 units³ approximately

Step-by-step explanation:

To find the volume of a cone with a diameter of 8 unit   and height of 6 units, we will follow the steps below;

first, write down the formula for calculating the volume of a cone

v= πr²\frac{h}{3}

where v is the volume of the cone

r is the radius    and h is the height of the cone

from the question given, diameter d = 8 units  but d=2r    which implies  r=d/2

r=8/2 = 4 units

Hence r= 4 units

height = 6 units

π is a constant and is ≈ 3.14

we can now proceed to insert the values into the formula

v= πr²\frac{h}{3}

v ≈ 3.14 × 4² × 6/3

v  ≈ 3.14 × 16 × 2

v ≈ 100 .48 units³

Therefore the  volume of the cone is  100 .48 units³ approximately
