OlgaM077 [116]

The percentage this empty space is of the entire volume is 26.12 % when rounded to the nearest tenth.

We have given that the shape of a

cylinder Container A has a diameter of 30 feet and a height of 18 feet.

diameter =30 feet and height =18 feet

Therefore

$radius=\frac{d}{2} \\\\radius=\frac{30}{2} \ \\\\radius=15$

What is the formula for volume of cylinder ?

$volume =\pi r^2h$

For cylinder A,

$volume =\pi r^2h$

$volume =\pi (15)^218\\ \\V=12723.45 ft^{3}$

Similarly for cylinder B,

h=19

radius

$\frac{26}{2} =13feet$

volume of cylinder B

$volume =\pi r^2h\\\\volume =\pi (13)^2(19)\\\\volume =10087.65 feet^3$

After pumping all of Cylinder A into Cylinder B there will remain empty space in B

$12723.45-10087.65=2635.8 feet^3$

The percentage this empty space is,

of the entire volume is

$\frac{2635.8}{10087.65} =0.261289$

which is 26.12 % when rounded to the nearest tenth.

Therefore,

The percentage this empty space is of the entire volume is 26.12 % when rounded to the nearest tenth.

Snoopy the dog is on a 25-ft long chain that is attached to the back of a barn (see the

NeTakaya

Answer:

A = 981.3 ft^2

Step-by-step explanation:

Here we're calculating the area of a semicircle of radius 25 ft.

The area of a circle is A = (pi)(r)^2, and that of a semicircle of the same radius is A = (1/2)(pi)(r)^2.

Here pi = 3.14 and r = 25 ft, and so the area/space in question is

A = (1/2)(3.14)(25)^2

A = 981.3 ft^2

Solve for k.<br> 6 1<br> 2k - 6 - 3

Taya2010 [7]

Answer:

k = 6.

Step-by-step explanation:

k = 6

2k = 12

12 - 6 - 3 = 3

k = 1

2k = 2

2 - 6 - 3 = -7

So, the answer is k = 6 because it makes more sense.
