Answer:
S = 2π(4)(16) + 2π(4²)
So option A is correct; S = 2 pi (4) squared + 2 pi (4) (16)
Step-by-step explanation:
The formula for total surface area of a cylinder is;
Total surface Area; S = 2πrh + 2πr²
Now,we are given;
Height;h =16 inches
Radius;r = 4 inches
Thus, plugging in the values into the Area formula, we have;
S = 2π(4)(16) + 2π(4²)
The correct answer from the options given is;
S = 2 pi (4) squared + 2 pi (4) (16)
If the angle above b is 54° then,
<h2>a = 54°</h2>
(Corresponding angles of a parallel line)
<h2>b = 126°</h2>
(Cause <b and 54° form a linear pair which is 180° and 180° -54° = 126°)
Answer:
we could buy 43 party favors
Step-by-step explanation:
initially we have an amount of $380
if we already spend an amount of $272 this we have to subtract it from the total
$380 - $272 = $108
if each party favor comes out $ 2.50 and we have $ 108 we have to divide what we have by what each one comes out to know how many we can buy
$108 / $2.50 = 43.2
this means we could buy 43 party favors
<span> x(4-k)=p
[x(4-k)=p]/x
4-k=p/x
-4 = -4
-k=p/x-4
k=4-p/x

Answer:
The cost of an oil change for 1 truck was $42
Step-by-step explanation:
Let
x -----> the cost of an oil change for 1 truck
y -----> the cost of gas for 1 truck
z ----> the total bill
we know that
![z=11[x+y]](https://tex.z-dn.net/?f=z%3D11%5Bx%2By%5D)
we have
substitute and solve for x
![694.32=11[x+21.12]](https://tex.z-dn.net/?f=694.32%3D11%5Bx%2B21.12%5D)
