= 2π (7) (11)

= 2π (77)

= 154π cm²

Gerald pours 441 cubic centimeters of liquid into the prism shown below. In the box, write the correct height of the liquidation

forsale [732]

The picture in the attached figure

we know that
[volume of the liquid]=[area of the base]*height
height=[volume of the liquid]/area of the base
volume of the liquid=441 cm³

area of the base=L*W
L=5 1/4 cm-----> (5*4+1)/4----> 21/4 cm
W=6 cm
area of the base=(21/4)*6-----> 31.5 cm²

height=[441 cm³]/31.5 cm²-----> 14 cm

the answer is
the height of the liquid is 14 cm

Margarita [4]

Answer

$\frac{ 6 {y}^{4} {w}^{2} }{{x}}$

Step-by-step Explanation

$\huge \frac{12 {x}^{3} {y}^{6} {w}^{5} }{ 2{x}^{4} {y}^{2} {w}^{3} } \\ \\ \huge= \frac{6 {x}^{3} {y}^{6} {w}^{5} }{{x}^{4} {y}^{2} {w}^{3} } \\ \\ \huge = 6 {x}^{3 - 4} {y}^{6 - 2} {w}^{5 - 3} \\ \\ \huge= 6 {x}^{ - 1} {y}^{4} {w}^{2} \\ \\ \huge = \frac{ 6 {y}^{4} {w}^{2} }{{x}^{1}} \\ \\ \huge = \frac{ 6 {y}^{4} {w}^{2} }{{x}}$
