r = 2 inches

total h of the cylinder = 6+6+6 = 18 inches

$SA = 2\pi {r}^{2} + 2\pi \: rh$

$= 2\pi \: r(r + h)$

$= 2 \times 3.14 \times 2(2 + 18)$

$= 2 \times 3.14 \times 2 \times 20$

$= 251.2square \: inches$

The sum of two positive integers, a and b, is at least 30. The difference of the two integers is at least 10. If b is th

Dafna11 [192]

Answer:

$a + b \geq 30$

$b - a \geq 10$

Step-by-step explanation:

Given

The sum of the two positive integer a and b is at least 30, this means the sum of the two positive integer is 30 or greater than 30, so we write the inequalities as below.

$a + b \geq 30$

The difference of the two integers is at least 10, if b is the greater integer then we subtract integer a from integer b, so we write the inequality as below.

$b - a \geq 10$

Therefore, the following system of inequalities could represent the values of two positive integers a and b.

$a + b \geq 30$

$b - a \geq 10$

Work out the size of angle x <br> Next to 164 and 90

Zielflug [23.3K]

Answer:

x=106 degrees

Step-by-step explanation:

I'm going to assume that this is a circle since you didn't give it to me

So you want to add 164 and 90 together and subtract the sum by 360

360-(164+90)=106

So you want to use PEMDAS (order of operations) to solve this

so do what's in the perenthesis first so 164+90=254
Then you want to subtract 254 from 360 so 360-254=106

x=106 degrees
