Answer: 188.4 ft^2

Step-by-step explanation:

Given, r= 3 ft, h= 7ft, pi = 3.14

Using the equation,

Surface area of cylinder= 2* pi * r (h+r) = 2* 3.14* 3 ft ( 3+7) ft = 188.4 ft^2

Which number line represents the solution to the inequality x - 3 > 2
Ivahew [28]

Answer: x > 5

Step-by-step explanation: To solve for <em>x</em> in this inequality, our goal is the same as it would be if this were an equation, to get x by itself on one side.

Since 3 is being subtracted from x, we add 3 to

both sides of the inequality to get x > 5.

When graphing x > 5, we have an open circle on 5 and the

open circle tells us that 5 is not part of our answer.

Then we draw an arrow going to the right to represent

all possible solutions to this inequality, any number greater than 5.

A line passes through the point (2, -9) and has a slope of -9. Write an equation in point-slope form for this line.
Natali [406]

Answer:

y+9 = - 9x +18

Step-by-step explanation:

Line is passing through the point (2,\: - 9) =(x_1,\:y_1) and has slope (m) = - 9

General equation of line in point slope form is given as:

y-y_1 = m(x-x_1)

Therefore

y-(-9) = - 9(x-2)

y+9 = - 9x +18

This is the required equation of line in point slope form.
