What is the volume of a hemisphere with a radius of 3 cm, rounded to the nearest tenth of a cubic centimeter?
Answers
The Volume of sphere whose radius is 3 cm = 113 (rounded to the nearest tenth)
Volume= 113
What is Volume of sphere?
The volume of a sphere = 4/3 r³, where r is the radius of the sphere.
Volume of sphere =
=
= 4 x 3.14 x 9
=113.04
≈ 113 (rounded to the nearest tenth)

Final answer:
The volume of a hemisphere with a radius of 3 cm is approximately 56.6 cm³ when rounded to the nearest tenth of a cubic centimeter. This is calculated by halving the volume of a sphere with the same radius.
Explanation:
Calculating the Volume of a Hemisphere
The question asks for the volume of a hemisphere with a radius of 3 cm. The formula for the volume of a sphere is V = (4/3)πr³, and since a hemisphere is half of a sphere, the formula adapts to V = (1/2)(4/3)πr³. Using a radius (r) of 3 cm, we get V = (1/2)(4/3)π(3 cm)³.
Let's calculate the volume step by step:
- First, calculate the volume of the full sphere using the radius of 3 cm: V = (4/3)π(3³) cm³
- Compute the result: V = (4/3)(π)(27) cm³ = (36π) cm³
- Since we want the volume of the hemisphere, we divide this number by 2: V = (36π/2) cm³ = (18π) cm³
- Finally, we approximate π to 3.142 and round to the nearest tenth: V ≈ 18(3.142) cm³ ≈ 56.6 cm³
Therefore, the approximate volume of the hemisphere is 56.6 cm³, when rounded to the nearest tenth of a cubic centimeter.

Explanation:
There is already 20 bags and 35 bags are filled per hour. So 35 is the rate of change and 20 is the constant
35x+20 ≥1,000
-20 -20
35x ≥980
Divide both sides by 35 to isolate x
=28
Flip the sign because you divided

normally you would subsiutte legnth for height when solving for the area of a triangle
if you have legnth, witdth, and height, then you have volume like volume of a fish tank
so
area=legnth times width
if you meant volume then if you have the area then
area=legnth times width
volume=legnth times width times height
so to solve for height when you know volume, area, legnth , width, then
divide both sides by (legnth times width or area)
volume/(legnth times width)=height

Rational numbers are closed under any set of operations.
Integers are not closed under division because 1/2 is not an integer.
The set {-1, 0, 1} is also not closed under division because -1/5 does not fall in that set.
Whole numbers are not closed under division because 5/3 will produce a number that is not a whole integer.
Your answer is A. rational numbers.
If you divide a rational number, it will remain a rational number. If you divide an integer or a whole number, there is a chance that the new resulting number will not be an integer or a whole number.
