The formula for the volume of a cylinder is v=piR^2h where v is the volume, R is the radius, and h is the height solve the formula for R and then use it to answer the question.
A cylindrical bucket contains 615 cubic inches of water. The height of the water is 4 inches
What is the radius of the bucket, to the nearest whole number? Use 3.14 for pi
Answer: Its 6
Step-by-step explanation: The answer is 5.99894 then you round it to 6.
The radius of the bucket, to the nearest whole number, is 7 inches.
So, option A. is correct.
Here, we have,
To solve the formula v = πR²h for R, we can rearrange the equation as follows:
v = πR²h
R² = v / (πh)
R = √(v / (πh))
Given that the volume v is 615 cubic inches and the height h is 4 inches, we can substitute these values into the equation:
R = √(615 / (3.14 * 4))
Calculating the value, we have:
R ≈ √(48.98)
R ≈ 7
Therefore, the radius of the bucket, to the nearest whole number, is 7 inches.
Hence, So, option A. is correct.

KN bisects ZJKM. If mZNKJ = 7x-9 and
m2JKM = x + 3, find m2JKN.
Answer:
Step-by-step explanation:
7x - 9 = x + 3
6x - 9 = 3
6x = 12
x = 2
7(2) - 9 + 2 + 3
14 - 9 + 5
5 + 5 = 10
solve for x: |12x + 12|=18
Answer:
x = 1/2 or x = -5/2
Step-by-step explanation:
Solve for x over the real numbers:
abs(12 x + 12) = 18
Hint: | Eliminate the absolute value.
Split the equation into two possible cases:
12 x + 12 = 18 or 12 x + 12 = -18
Hint: | Look at the first equation: Isolate terms with x to the left hand side.
Subtract 12 from both sides:
12 x = 6 or 12 x + 12 = -18
Hint: | Solve for x.
Divide both sides by 12:
x = 1/2 or 12 x + 12 = -18
Hint: | Look at the second equation: Isolate terms with x to the left hand side.
Subtract 12 from both sides:
x = 1/2 or 12 x = -30
Hint: | Solve for x.
Divide both sides by 12:
Answer: x = 1/2 or x = -5/2

An object is moving at a speed of 9 centimeters every 5.5 minutes. Express this speed in miles per day. Round your answer to the nearest hundredth.
An object is moving at 9 centimeters every 5.5 minutes have a speed of 0.01 mile per day.
Speed is the ratio of distance travelled to time taken. Speed is given by:
Speed = distance/time
Given that the 9 cm is covered every 5.5 minutes, hence:
1 mile = 160934 cm;
9 cm = 9 * 1/160934 = 9/160934 mile
1 day = 1440 minutes
5.5 minute = 5.5 * 1/1440 = 5.5/1440 day
Hence:
Speed = distance/time
Speed = (9/160934 mile)/(5.5/1440 day)
Speed = 0.01 mile per day
An object is moving at 9 centimeters every 5.5 minutes have a speed of 0.01 mile per day.

1. A point is named or labeled using? 2. Three distinct points are collinear if ? 3. Three distinct points are coplanar if ? PLZ HELP
Answer:
1) A point P is named or labeled by using a coordinate pair, where the regular notation is:
P = (x, y).
Where x and y are the horizontal and vertical components.
2) Three distinct points are collinear if exists a line that passes through the 3 points.
3) Three distinct points are complanar if they are not collinear, this means that:
We can have two colinear points (so one line connects them) and another point outside that line.
Then the set of 3 points is coplanar.
