A sphere has a radius of 5 feet. Find the volume of the sphere. Leave your answer in terms of pie. Then use 3.14 for pie and round the volume to the nearest 10th. Volume in terms of pie=? Volume in using 3.14=?
Answers
Solution: V=4
3πr3=4
3·π·53≈523.59878 and 5 or more raise the score so the 9 makes the 5 into 6 and drop all of the other numbers
The solution is, The Volume is 523.6, of the sphere has a radius of 5 feet.
What is volume?In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
here, we have,
Given,
r = 5 ft
pi = 3.14
Formula
the volume of sphere is:
V = 4/3 * 3.14 * r^3
Solution
V = 4/3 * 3.14 * 5^3
V = 4/3 * 3.14 * 125
V ≈ 523.59878
V ≈ 523.6 m^3
as, we get,
V≈523.59878
and 5 or more raise the score so the 9 makes the 5 into 6 and drop all of the other numbers.
Hence, The solution is, The Volume is 523.6, of the sphere has a radius of 5 feet.

A plumber has a 2-meter length of pipe. He needs to cut it into sections that are 10 centimeters long. How many sections will he be able to cut? (I will give brainliest if you answer first)
Answers
Answer:
20 - 10 cm sections can be cut from a pipe of original length 2 m
Step-by-step explanation:
Convert 2 meters to cm:
2 m 100 cm
------ * ---------------- = 200 cm
1 1 m
Next, divide this 200 cm total length by (10 cm/section) to determine the number of sections:
200 cm
--------------------- = 20 sections
10 cm/section
20 - 10 cm sections can be cut from a pipe of original length 2 m

Answers
4m^2 - 14m - 14m + 49
4m^2 - 28m + 49
Answer: 4m²-28m+49
Step-by-step explanation:
(2m-7)² can be written as (2m-7)(2m-7).
You would have to multiply it out like this:
2m times 2m=4m² (2x2=4 and mxm=m²)
2m times -7=-14m (2x-7=-14 then put a m on it)
-7 times 2m=-14m
-7 times -7=49
The equation would then look like this:
4m²-14m-14m+49
Then you would have to collect like terms. Like terms are terms with the same variables and powers. It will then look like this:
4m²-28m+49

It should be D, [tex]x^4 - 2x^3 + 7x^2 -12x - 4[/tex]
Step-by-step explanation:
Since, the equation given in the question is the factored form of the equation D. It can be solved using FOIL (First Outside Inside Last):
x * x³ = [tex]x^{4[/tex]
x * 7x = 7x²
x * 2 = 2x
-2 * x³ = -2x³
-2 * 7x = -14x
-2 * 2 = -4
This all would add up to ⇒ [tex]x^{4}[/tex] - 2x³ + 7x² + (-14x + 2x) -4
Simplifying the parenthesis further would give the option D as the answer.
