The lateral area of a right cylinder which has a base diameter of 12 cm and a height of 8 cm is?
garik1379 [7]

Answer:

A = 301.59\ cm^2 or A=96\pi\ cm^2

Step-by-step explanation:

The lateral area of a cylinder is calculated by the following formula

A = 2\pi r * h.

Where r is the radius of the right cylinder and h is the height

In this case we know that the diameter d of the cylinder is

d=2r\\\\r=\frac{d}{2}\\\\r=\frac{12}{2}\\\\r=6\ cm

h=8\ cm

Therefore the lateral area is:

A = 2\pi*6 * 8.

A = 96\pi

A = 301.59\ cm^2

Please do not do this for the points, it's rude and disrespectful. I really need help.
professor190 [17]

Answer:

1) A = -10, B = -4, distance = 6 units

2) Eqaution: 3(x+4) = 60

Tyler's age: 16 Samantha: 20

3) x < 1

Draw a number line from 1 towards left, with an open circle at x = 0

Step-by-step explanation:

1) A/2 = -5

A = -5×2 = -10

8 = -B/0.5

8×0.5 = -B

B = -4

Distance = -4 - (-10) = -4 + 10 = 6

2) S = 4 + x

3s = 60

3(4 + x) = 60

3S = 60 S = 20

4 + x = 20 x = 16

3) x/2 + ¼ < ¾

x/2 < ¾ - ¼

x/2 < ½

x < 1

Draw a number line going towards left from 1, with an open circle at x=1 because x=1 is not included
