Answer:

22.88 cm^3

Step-by-step explanation:

The volume of a sphere formula is (4/3)*pi * (radius)^3

Since the diameter is 5.08cm, we divide by 2 to find the radius which is 2.54 cm.

Also because of the fact that 2/3 is showing outside the cone, that means 1/3 is inside the cone. Therefore, we have to multiply the volume by 1/3.

We have:

Volume = (4/3) * pi * (2.54)^3 * (1/3)

= 22.88 cm^3

What is the equation of the line that is paralle to y=3x-8 and passes thur the point (4,-5)
Brrunno [24]

⊰_________________________________________________________⊱

Answer:

  • The equation is-: y=3x

Step-by-step explanation:

\large\displaystyle\text{$\begin{gathered} \sf{Substitute \ the \ values \ into \ the \ formula \ y-y_1=m(x-x_1)} \\ \sf {parallel \ lines \ have \ same \ slopes, \ thus} \\ \sf{slope \ of \ the \ 2nd \ line = 3}\\ \sf{now \ substitute \ the \ values} \\ \sf {y-(-5)=3(x-4)}\\ \sf{y+5=3(x-4) (It's \ Point-Slope\;Form, \ see \ below \ for \ slope-intercept)}\\ \sf {y+5=3x-12} \\ \sf{y=3x-12-5} \\ \sf{y-3x-17} \end{gathered}$}}

Find the Volume. Use pi=3.14. Round to the nearest hundredth.
aleksandr82 [10.1K]
<h2>Volume = 4.19 inches³</h2>

<u>Step-by-step explanation:</u>

radius = 1 inches

π = 3.14

volume of SPHERE = 4/3 × π × radius³

= 4/3 × 3.14 × 1³

= 4.19 inches³
