Only c. using cross multiplication , it shows the correct percent. 6.0 does not work because that would imply that it is 600% rather than 60 percent

Find the volume of the cylinder express your answers in terms of pi

Serjik [45]

Answer:

704 pi in ^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h where r is the radius and h is the height

V = pi ( 8)^2 * 11

V = pi (704)

V = 704 pi in ^3

Write the standard equation of the circle with center (-14, -3) that passes through the point (-5,3),

grin007 [14]

Answer:

$(x + 14)^2 + (y + 3)^2 = 117$

Step-by-step explanation:

Equation of a circle:

The equation of a circle with center $(x_0,y_0)$ is given by:

$(x - x_0)^2 + (y - y_0)^2 = r^2$

In which r is the radius.

Center (-14, -3)

This means that $x_0 = -14, y_0 = -3$

$(x - x_0)^2 + (y - y_0)^2 = r^2$

$(x - (-14))^2 + (y - (-3))^2 = r^2$

$(x + 14)^2 + (y + 3)^2 = r^2$

Passes through the point (-5,3),

This means that when $x = -5, y = 3$ . We use this to find the radius squared. So

$(x + 14)^2 + (y + 3)^2 = r^2$

$(-5 + 14)^2 + (3 + 3)^2 = r^2$

$r^2 = 117$

So, the equation of the circle is:

$(x + 14)^2 + (y + 3)^2 = r^2$

$(x + 14)^2 + (y + 3)^2 = 117$

What is the volume of a cone with a height of 6m and a diameter of 12m? Nearest meter.

AlexFokin [52]

Answer:

0.0005m^3

Step-by-step explanation:

V=1/3hπr²

h=6m

d=12m

r=12÷2=6m

V=1/3×6×(3.14)×36

V=1/2034.72

V=0.0005m^3

komal went on vacation and bought three shirts for $11.21 each she paid $2.40 for a keychain and $6.47 for a mug. she also spent

mash [69]

The total amount of money which komal spent during her vacation is

$65.67

Given, Komal bought 3 shirts for $11.21 each.

She also spent her money on a keychain for $2.40 and a mug for $6.47.

After that she spent $23.17 for getting her picture developed.

How much in total she spend her money = ?

Money spent on shirts:

Cost for one shirt = $11.21

cost for three shirts = 3 × 11.21

= $33.63

Now add the amount of all the items Komal bought for herself.

Total money spent = cost price of shirts + cost price for a keychain + cost price for a mug + cost price for getting a picture developed.

Total money spent = 33.63 + 2.40 + 6.47 + 23.17

Total money spent = $65.67

Hence the total money Komal spent is $65.67.
