I do need help with this problem that includes pi. ^_^
Answers
Solution:
Note that:
Circumference = 50.24 ft = 2πr = πdDia. = 16 ft.Divide the diameter both sides.
50.24 ft = πd=> 50.24/d ft = πd/d=> 50.24/d ft = πSubstitute the diameter in the equation.
=> 50.24/16 = π (Option A)Solving proportions

The GCD and LCM of three numbers are 3 and 1008 respectively.If two of the numbers are 48 and 72.Find the least possible value of the third number
Answers
Answer:
21
Step-by-step explanation:
We decompose prime factors of 48, 72, and 1008
48=2*2*2*2*3
72=2*2*2*3*3
1008=2*2*2*2*3*3*7
Let's compare 48, 72 with GOD(3) and LCM(1008), we can find that there must be at least 2 prime factors in the third number that is 3 and 7.
And let's find out the LCM of 48 and 72. Quite obvious the answer is 144.
Since the LCM should be the consequence of 144 multiplied by another prime factor.
Then let's try 144*7. Amazingly 144*7=1008. DONE!

Point L is on line segment KM. Given LM = 5 and KM=9, determine the length KL.
Answers
Answer:
KM=LM+KL. If KM is 9 and LM is 5, then KM-LM=KL. So 9-5=4. KL is 4.
Step-by-step explanation:
The value of KL will be equal to 4 in the line segment KM.
What is a line segment?A line segment in geometry is a section of a line that has two clearly defined endpoints and contains every point on the line that lies within its confines.
Given that point, L is on line segment KM. Given LM = 5 and KM=9. The value of the line segment KL will be calculated as below:-
KM = LM + KL.
If KM is 9 and LM is 5, then,
KM-LM=KL.
KL = 9-5=4.
KL = 4
Therefore, the value of KL will be equal to 4 in the line segment KM.

A can of paint covers approximately 400 sq ft. How many cans of paint will I need to buy? Number only. Do not label.
