Answer:
The cross section of sphere is circle
Area of cross section = 25 in²
Step-by-step explanation:
From the figure we can see a cylinder with height 8 inches and volume 200 π in³.
<u>The cross section of the cylinder looks like a circle.</u>
<u>To find the area of cross section</u>
Volume of cylinder = Cross section area * Height
200 = cross section area * 8
cross section area = 200/8
= 25 in²
Area of cross section = 25 in²
Answer:
The formula for the volume of a sphere is V = 4/3 πr³.
Step-by-step explanation:
Surface area of sphere = 4πr2
Volume of a sphere = 4/3 πr3
You only need to know the radius to figure both the volume and surface area of a sphere.
Answers for surface area problems should always be in square units.
Answers for volume problems should always be in cubic units.

Step-by-step explanation:
Answer:
d. (75 / 100) * 100
Step-by-step explanation:
Pathogen is best described as cross contaminant which a bacteria or a virus that causes infection or disease in human. The lab tests confirms that total percentage of attendees who are infected by the disease is 75%. The total attendees were 100 out of which 75 had been infected and 50 demonstrated symptoms of the illness.
Answer: The ordered pair is (2,3)
Step-by-step explanation:
To solve this problem, we can use substitution. With substitution, we substitute the y in each problem with the equations. In this case, x + 1 can substitute the y in y = -x + 5. Here is what the problem looks like now:
x + 1 = -x + 5
The reason we used substitution is because we assume that these linear equations are equal. We must prove it, though. We can use algebra.
Move the variables to one side and the numerical values to another:
x + x = 5 - 1.
Simplify.
2x = 4
Simplify.
x = 2.
Now, we got our x value, we can substitute it into our problem:
y = 2 + 1
y + -2 + 5
2 + 1 = - 2 + 5 = 3
Our x is 2, and our y is 3. The ordered pair that is a solution is (2,3).
