Answer:
C
Step-by-step explanation:
3 1/2 times -(4/5)
First multiply 3 1/2 and -(4/5)=2 4/5
For this case we have that the perimeter of the figure is given by the sum of the lengths of the sides, that is:

Thus, the perimeter of the figure is 64 centimeters.
Now, we find the area of the figure:
We have that by definition, the area of a rectangle is given by:

Where:
a and b are the sides of the rectangle
We have 4 vertical rectangles from left to right:

Thus, the total area is
Answer:
The perimeter of the figure is 64 centimeters.

Answer:
B
Step-by-step explanation:
So we have the formula:

And we want to solve it for r.
So, let's first divide both sides by π and h. This will cancel out the right side:

Now, take the square root of both sides:

And we're done!
Our answer is B.
I hope this helps!
Answer:
Step-by-step explanation:
you have to multiply
Answer:
v = 18π
Step-by-step explanation:
v = πr²h
plug in the givens
v = π(3²)2
v = 18π exact answer
V = 18 * 3.14 = 56.52 decimal approximation
