Find the volume of the cylinder.<br> Either enter an exact answer in terms of π or use 3.14 for π

Alex787 [66]

Answer:

Volume of the cylinder = $62.80 units^3$

Step-by-step explanation:

Height of the Cylinder(h)=5 units

Radius(r)=2 units

Volume of a cylinder= $\pi *r*r*h$

Putting the values in the formula;

Volume of the cylinder $=\pi *2*2*5$

As, $\pi =\frac{22}{7}=3.14$

Volume of the cylinder= $3.14*2*2*5$

$=3.14*2*2*5\\\\=3.14*4*5\\\\=3.14*20\\\\=62.80units^3$

The Volume of the cylinder is $62.80 units^3$

Y = -4/3x − 1<br> y = 1/3x + 4

Tom [10]

Answer:

x = -3, y =3

Step-by-step explanation:

y = -4/3x - 1

y = 1/3x + 4 -------> 4y = 4/3x + 16

Adding the first equation and the new second equation together:

5y = 15 ------> y = 3

Plug y = 3 into one of the original equations:

3 = 1/3x + 4

-1 = 1/3x

x = -3
