1/4x. You didn't give us any answer choices, so if that's wrong I apologize but I doubt it is.

What is the volume of the composite figure? 12in 4 in 3 in. 7 in.

Minchanka [31]

Answer:

Step-by-step explanation:

$V_p = b \cdot h \cdot w$ , where b, h, w are base, height and width respectively.

$V_{sp} = \frac{1}{3} \cdot {A_b} \cdot h$ , where h is the height, and A_b is the area of the base.

First let's calculate the volume of the paralelipiped by the first formula.

$V_p = 7 \cdot 4 \cdot 3 = 84 in^2$

Then let's find out the height of the pyramid, which is 12 - 4 = 8 in.(See drawing)

Then the area of the base of the square pyramid is simply.

$A_r = 3 \cdot 7 = 21 in^2$

Now we can find the volume of the pyramid.

$V_{sp} = \frac{1}{3} \cdot 21 \cdot 8 = 56 in^3$

To find the total volume, let's add both volumes.

$V_T = 84 + 56 = 140 in^3$

A fence is to be built to enclose a rectangular area of 260 square feet. The fence along three sides is to be made of material t

Nat2105 [25]

Answer:

Length of the rectangle = 9.58 feet and width = 27.14 foot

Step-by-step explanation:

Let the length of the rectangular area is = x feet

and the width of the area = y feet

Area of the rectangle = xy square feet

Or xy = 260

y = $\frac{260}{x}$ -------(1)

Cost to fence the three sides = $3 per foot

Therefore cost to fence one length and two width of the rectangular area

= 3(x + 2y)

Similarly cost to fence the fourth side = $14 per foot

So, the cost of the remaining length = 14x

Total cost to fence = 3(x + 2y) + 14x

Cost (C) = 3(x + 2y) + 14x

C = 3x + 6y + 14x

= 17x + 6y

From equation (1)

C = $17x+\frac{260\times 6}{x}$

Now we take the derivative,

C' = 17 - $\frac{1560}{x^{2} }$

To minimize the cost of fencing,

C' = 0

17 - $\frac{1560}{x^{2} }$ = 0

$\frac{1560}{x^{2} }$ = 17

$x^{2} =\frac{1560}{17}$

$x=\sqrt{\frac{1560}{17} }$

x = 9.58 foot

and y = $\frac{260}{9.58}$

y = 27.14 foot

Pls help !!

Area of circle= πr² so, our radius would be 5in because the diameter is 10 in which makes our sum to be π×5²= 78.5 in

Circumference of circle= 2πr so, 2×5×π= 31.4 in
