Answer:
18
Step-by-step explanation:
Alright so here you have to work backwards. the volume of a cylinder is pi*r^2*h.
Your equation: 486 pi = pi*r^2*6
You know the height is 6 feet, so you can get rid of the 6 feet hanging off of your equation by dividing both sides by 6:
81 pi = pi*r^2
Now you notice that both sides have pi. You can eliminate it by dividing both sides by pi:
81 = r^2
To isolate the r, radius, you have to take the square root of both sides, since a square root is the inverse operation of squaring. You get:
9 = r
Now that you have the radius, you can find the diameter by multiplying the radius by 2, because a diameter = 2 * the radius:
18 = d
Hope this helps!
Answer:
-2/5
Step-by-step explanation:
The slope of two parallel lines will be the same.
Here, our equation is 5y + 2x = 12. Let's find the slope by isolating y:
5y + 2x = 12
5y = -2x + 12
y = (-2/5)x + 12/5
So, the slope is -2/5.
Thus, the slope of the line parallel to the given one will be -2/5.

Answer:
Construct the perpendicular bisectors of each side
Choice A is correct
Step-by-step explanation:
Circumscribe means to draw on the outside of a geometric figure just touching the corner points but never crossing.
The steps in constructing a circle circumscribed about a triangle;
Construct the perpendicular bisector of one side
Construct the perpendicular bisector of another side
Where the lines cross is the center of the Circumscribed circle

Answer:
The annual interest rate is 12.05%.
Step-by-step explanation:
The simple interest is given by the formula:
Where I denotes interest.
P denotes the principal amount.
R denotes the rate of interest
and T denotes the time period.
I=$160.67, P=$2000, t=8 months=8/12 years (Since 12 months=1 year so 1 month=1/12 year)
Hence, the annual interest rate is 12.05%.
