A spherical ball just fits inside a cylindrical can, 20 centimeters tall, with a diameter of 20 centimeters. Which expression gi

soldier1979 [14.2K]

Answer:

B. $\frac{4}{3}\pi (10)^3$

Step-by-step explanation:

Given:

A spherical ball just fits inside a cylindrical can, 20 centimeters tall, with a diameter of 20 centimeters.

diameter of Sphere = 20 centimeters

hence radius = half of diameter = $\frac{1}{2}\times 20 = 10\ cm$

Hence we need to find the volume of sphere.

Volume of sphere = $\frac{4}{3}\pi r^3$

Here r is the radius of the circle.

Hence Volume of sphere = $\frac{4}{3}\pi (10)^3$

Hence Option B $\frac{4}{3}\pi (10)^3$ is the correct answer.

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}$}}$
