The formula for the volume of a sphere is V=(4/3) (pi) r^3. if r is doubled then you get 2r as the radius and V=(4/3) (pi) * 8r^3 so the volume is eight times bigger than the original r value. if r is tripled the r =3r and (3r)^3 so the volume is 27 times bigger. If r is multiplied by n the radius is nr and (nr)^3 =n^3 r^3, Therefore, the volume is n^3 times bigger than the original.
the answer shoulldd be 136°
Answer:
x = 3
Step-by-step explanation:
<u>Step 1: Plug in 12 for y</u>
<em>2x - 18 = -2(12) + 12</em>
<em />
<u>Step 2: Multiply</u>
<em>2x - 18 = -24 + 12</em>
<em />
<u>Step 3: Combine</u>
<em>2x - 18 = -12</em>
<em />
<u>Step 4: Add 18 to both sides</u>
2x - 18 + 18 = -12 + 18
<em>2x = 6</em>
<em />
<u>Step 5: Divide both sides by 2</u>
2x / 2 = 6 / 2
<em>x = 3</em>
<em />
