The formula for finding volume of a cylinder is: π · r² · h

$r = 6 \\ r^{2} = 6 \times 6 = 36$

$h = 8$

Now multiply

$\pi \times 36 \times 8 = 288\pi$

Your answer is C)288π units³

Answer:

h = 0.64 ft

Step-by-step explanation:

$s = \frac{14 + 12 + 6}{2} = \frac{32}{2} = 16 \: ft \\ \\ A = \sqrt{(s - 14)(s - 12)(s - 6)} \\ \\ A = \sqrt{(16 - 14)(16 - 12)(16 - 6)} \\ \\ A = \sqrt{(2)(4)(10)} \\ \\ A = \sqrt{80} \\ \\ A = 8.94427191\\ \\ A \approx 8.94 \: {ft}^{2}$

A = 14h

8.94427191 = 14h

h = 8.94/14

h = 0.638571429

h = 0.64 ft

-9 + p/2= -13 <br> (two step equations, show your work)

malfutka [58]

Answer:

p=−8

Step-by-step explanation:

Regroup terms.

p /2 −9=−13

Add 9 to both sides.

p/2 =−13+9

Simplify -13+9 to −4.

p/2=−4

Multiply both sides by 2.

p=−4×2

Simplify 4×2 to 8
