Circumference formula: 2πr
Diameter: 2r
1: 15×3.14= 47.1 in
2. AB is radius so use circumference formula to solve for r
20=2πr
20=6.28r
R=3.18 cm or 3.2 cm

  • Volume=2.7million km^3
  • Base=339milliom km^2

\\ \tt\longmapsto Volume=Base\times Height

\\ \tt\longmapsto Height=\dfrac{Volume}{Base}

\\ \tt\longmapsto Height=\dfrac{2.9km^3}{339km^2}

\\ \tt\longmapsto Height=0.00079km

\\ \tt\longmapsto Height=7.9m

(x+3)²(65)=x(6)<br>Solve using quadric formula​
Angelina_Jolie [31]

Step 1: Simplify both sides of the equation.

  • 65x²+390x+585=6x

Step 2: Subtract 6x from both sides.

  • 65x²+390x+585−6x=6x−6x
  • 65x²+384x+585=0

For this equation: a=65, b=384, c=585

  • 65x²+384x+585=0

Step 3: Use quadratic formula with a=65, b=384, c=585

  • x=−b±√b2−4ac/2a
  • x=−(384)±√(384)2−4(65)(585)/
  • 2(65)
  • x=−384±√−4644/130

Therefore, There are no real solutions.

How do you decide where to put a point when you are graphing?
elena55 [62]

Step-by-step explanation:

When deciding where to put an ordered pair on a graph its important to understand how ordered pairs work.

An ordered pair is split up into to pieces

(x,y) or number example (3,5)

When graphing the x coordinate will fall on your horizontal line or the line that looks like the horizon.

When graphing the y coordinate it will fall on your vertical line or the line that goes right up into the sky like a rocket.  

To graph (3,5)

Go to the right 3 and up 5

Sometimes helps to use both fingers to keep your spot. Slide both fingers until they collide and that's where you would plot your point!

Hope this helps if you have an questions just comment and ill try to explain further.
