Answer:
A=640.88
Step-by-step explanation:
if the diameter is 12, the radius , r=12/2=6
we have r=6, h=11
Surface area, A= 2πrh+2π r^2
A=2*3.14*6*11+2*3.14*(6)^2=640.88
Answer:
D. $1.95
F. $3
Step-by-step explanation:
dimes: x + 2
quarters: x
x + 2 + x = 12
2x + 2 = 12
2x = 10
x = 5
dimes: x + 2 = 5 + 2 = 7
quarters: x = 5
Total value: (7 * .10) + (5 * .25) = $1.95
_____
dimes: x
quarters: 2x
x + 2x = 15
3x = 15
x = 5
dimes: x = 5
quarters: 2x = 2(5) = 10
Total value: (5 * .10) + (10 * .25) = $3
Pq= 10.5, qr=31.5, rs=10.5, sp=31.5
Answer:

Step-by-step explanation:
Given inequality:

In order to represent the solution on the number line, we will first solve the given inequality.
We have

Subtracting both sides by 4.


Dividing both sides by -3.
[On dividing both sides by a negative number the sign of the inequality reverses.]

So, solution of this inequality will range from -3 to -∞
The number line is represented below.
