Answer:

Step-by-step explanation:

r = 14/2 = 7units

$Volume of sphere=\frac{4}{3}*\pi*r^{3}\\\\=\frac{4}{3}*3.14*7*7*7\\\\=1436.03cubic units\\\\Volume of cylinder=\pi*r^{2}*h\\\\=3.14*7*7*14\\\\=2154.04 cubic units$

Write an equation of each line in standard form with integer coefficients.<br> 4. y = 2.4x + 1.8

Nadusha1986 [10]

Answer:

Step-by-step explanation:

The standard form of an equation of a line:

$Ax+By=C$

We have

$4y=2.4x+1.8$

Convert

$4y=2.4x+1.8$ <em>multiply both sides by 10</em>

$40y=24x+18$ <em>subtract 24x from both sides</em>

$-24x+40y=18$ <em>change the signs</em>

$24x-40y=-18$ <em>divide both sides by 2</em>

$12x-20y=-9$
