Answer: -416/1575

Step-by-step explanation:

$\frac{4}{5}=\frac{20}{25} \implies \frac{4}{5}+\frac{6}{25}=\frac{26}{25}\\$

$\frac{8}{9}=\frac{56}{63}\\\\-\frac{8}{7}=-\frac{72}{63}\\\\\implies \frac{8}{9}-\frac{8}{7}=-\frac{16}{63}$

$\frac{26}{25} \times -\frac{16}{63}=-\frac{416}{1575}$

What is the volume of a cylinder, in cubic centimeters, with a height of 8 centimeters

Arisa [49]

Answer:

1608.5 cm³

Step-by-step explanation:

Use the cylinder volume formula, V = $\pi$ r²h

If the diameter is 16 cm, then the radius is 8 cm.

Plug in the radius and height into the formula, and solve:

V = $\pi$ r²h

V = $\pi$ (8)²(8)

V = $\pi$ (64)(8)

V = 1608.5

So, to the nearest tenth, the volume of the cylinder is 1608.5 cm³

What is the answer? I'll give brainiest to whoever is right

drek231 [11]

Answer:

5) 0 6 ) 1/4

Step-by-step explanation:

So the slope ( gradient ) of line E is 0 because it is straight and it as no slope

The slope of line F is 1/4 because:

Gradient = y^2 - y^1 / x^2 - x^1

Gradient = 2-0 / 6- -2

Gradient= 2 / 8

2/8 in lowest term is 1/4
