Which case would be the most appropriate

AleksAgata [21]

Answer:

Case (c) will be the most appropriate for a drum with a volume of 14,000 cm³

Step-by-step explanation:

The drum is in the shape of cylinder so, we will calculated its volume using formula :<u> V = πr²h</u> , where r is radius of cylinder and h is height of cylinder.

In case (a) Given height is 300mm ( 30 cm ) and diameter is 200mm ( 20 cm )

so, radius ( r ) is calculated as d/2

r = 20/2

r = 10 cm

so, volume is V = πr²h = (3.14)*(10)²*30 = 9420 cm³

In case (b) Given height is 30 cm and diameter is 400mm ( 40 cm )

so, radius ( r ) is calculated as d/2

r = 40/2

r = 20 cm

so, volume is V = πr²h = (3.14)*(20)²*30 = 37680 cm³

In case (c) Given height is 250mm ( 25 cm ) and diameter is 32 cm

so, radius ( r ) is calculated as d/2

r = 32/2

r = 16 cm

so, volume is V = πr²h = (3.14)*(16)²*25 = 20096 cm³

Hence, the case (c) will be the most appropriate for a drum with a volume of 14,000 cm³

Please help me with this one.

borishaifa [10]

Answer:

V = 16
W = 48

Step-by-step explanation:

The triangles are congruent when corresponding sides are congruent.

__

ΔFGH ≅ ΔABC means corresponding sides are ...

(GH, BC) = (V, 16)

(HF, CA) = (48, W)

Corresponding sides being congruent means ...

V = 16

W = 48

<h3>The surface area of cube is 162.24 square inches</h3>

<em><u>Solution:</u></em>

<em><u>The surface area of cube is given as:</u></em>

$Surface\ Area = 6s^2$

Where,

"s" is the length of each side of cube

From given,

s = 5.2 inches

Therefore,

$Surface\ Area = 6 \times 5.2^2\\\\Surface\ Area = 6 \times 27.04\\\\Surface\ Area = 162.24$

Thus the surface area of cube is 162.24 square inches
