You need to use the distance formula to find the radius of the circle.
The radius is 3.
The circumference is
Answer:
D. 3x+(-2)=2x+4
Step-by-step explanation:
There is 2 red cubes of -1 so it has to be in parentheses, not combined like letter C.
Answer:
The length of the portion BC of the cloth is 4.56 inches long.
Step-by-step explanation:
I suggest drawing the triangle out! It'll make it a lot easier to solve!
A
|35\ 8 inches
| \
B |90 _\ C
x inches
Here you can use SOH CAH TOA
SOH = Sin theta = Opposite/Hypotenuse
CAH = Cos theta = Adjacent/Hypotenuse
TOA = Tan theta = Opposite/Adjacent
We are going to use Sin because we have the hypotenuse and we're solving for opposite.
Sin theta (angle) = Opposite/Hypotenuse
Sin (35) = x/8
Sin (35) = 0.57 (Use a calculator)
0.57 = x/8 Now we're going to solve for x (segment BC)
0.57*8 = x
4.56 = x
The length of the portion BC of the cloth is 4.56 inches long.
Answer:
Step-by-step explanation:
The volume of a cylinder is defined as
So, by given we know that the diameter of the circular base is times its height which is , if we transform each mixed number into a fraction, it would ne
Diameter: times the height.
Height:
That means,
, replacing the height, we have
But, the radius is half the diameter by definition
Now that we know the radius and the height, we can use the formula to find the volume
Therefore, the volume rounded to the nearest hundred is
