Find the volume of the cylinder.<br> 1607.7 in 3<br> 2845.7 in 3<br> 6430.7 in 3<br> 401.9 in 3

Musya8 [376]

Answer:

$\Huge\boxed{1607.7in^3}$

Step-by-step explanation:

Hello There

The volume of a cylinder can be found using this formula

$V=\pi r^2h$

where r = radius and h = height

The cylinder shown has a radius of 8 inches and a height of 8 inches

Knowing this information we plug it in into the formula

$V=\pi 8^28\\8^2=64\\64*8=512\\512\pi=1607.68$

Finally we round to the nearest tenth and get that the volume of the cylinder is 1607.7 in ^3

Please help with the following problem asap!!

Answer:

$8^7$

Step-by-step explanation:

$\dfrac{8^{15}}{8^7 \cdot 8} =$

Remember that $8 = 8^1$ .

$= \dfrac{8^{15}}{8^7 \cdot 8^1}$

When you multiply powers with the same base, add the exponents. Do this in the denominator.

$= \dfrac{8^{15}}{8^{7+1}}$

$= \dfrac{8^{15}}{8^{8}}$

When you divide powers with the same base, subtract the exponents.

$= 8^{15-8}$

$= 8^7$

How do I solve for c and y 72x+84y=4920

Aleksandr [31]

Answer:

y = -6/7 + 410/7

(y = mx + c)

Step-by-step explanation:

72x + 84y = 4920

84y = -72x + 4920

y = -6/7 + 410/7
