Please help me on a test 2 3/4 + 5 1/2

drek231 [11]

Answer: 8 1/4

Step-by-step explanation:

2 3/4 + 5 1/2 = ?

Least common denominator is 4

2 3/4 + 5 2/4 = ?

2(4)+3 = 11

5(4) + 2 = 22

so the equation becomes

11/4 + 22/4 = 33/4 = 8 1/4

Find the exact area of a circle having the given circumference.

blagie [28]

Answer:

Step-by-step explanation:

The formula of an area of a circle:

$A=\pi r^2$

r - radius

The formula of a circumference of a circle:

$C=2\pi r$

We have:

$C=3\pi$

Substitute:

$2\pi r=3\pi$ <em>divide both sides by 2π</em>

$r=1.5$

Substitute:

$A=\pi(1.5)^2=2.25\pi$

Please i need help on my math

Kamila [148]

Answer:

$V = \pi (2.5)^2h$

Step-by-step explanation:

The formula for the volume of a cylinder, is V = π r^2 h. It shows that the diameter is 5. But we need the radius. The radius is half of the diameter. So, 5/2. This gets you 2.5.

The equation is now:

V = π(2.5)^2h

This is the answer.

$V = \pi (2.5)^2h$

professor190 [17]

Answer:

Step-by-step explanation:

In order to be a function you should have one output for every input (or one y for every x). In this case there are multiple outputs for the number one which means the relationship isn't a function
