Answer:
Part A: <u>Which point represents the origin? </u>
- The origin is the point with both zero coordinates: (0, 0)
Part B: <u>Starting from the origin, explain how to plot the following three points accurately (1,-1) (-1.1.25) (-2,3).</u>
Reference point is the origin for below.
- (1,-1) - go <u>right </u>by 1 unit and <u>down </u>by 1 unit, plot the point
- (-1.1.25)- go <u>left </u>by 1 unit and <u>up </u>by 1.25 or 1 and 1/4 units, plot the point
- (-2,3) - go <u>left </u>by 2 units and <u>up</u> by 3 units and plot the point
To solve this problem you must apply the proccedure shown below:
You have that the radius of the cylinder is 2.75 inches and the height is 5.21 inches. Therefore, you only need to substitute these values into the formula for calculate the volume of a cylinder:
Therefore, as you can see, the answer is: The volume of the cylinder is 124 in³.
Answer:
(1,4)
Step-by-step explanation:
Basically, you are asked to find the volume of a cylinder with a diameter of 14 inches and a height of 18 inches. The formula for the volume of a cylinder is
V = pi*(r^2)*h
r is just the half of the diameter. In this case, r = 14/2 = 7. Then,
V = pi*(7^2)*18
V = 2771 cubic inches
