Answer:
20π
Step-by-step explanation:
Area = πr^2
100π = πr^2
solve for r and r = 10
circumference of a circle is 2πr
therefore 2π×10=20π in
Answer:
6m-5
Step-by-step explanation:
first you have distribute the negative to the equation in the parentheses so you get
8m - 5 - 2m
Then combine the like terms
So the final answer is 6m-5
Part 1:
The pattern for the first sequence goes by the multiples of 12 and you can show your work by adding 12 to the following number. Example:
12 + 12 = 24
24 + 12 = 36
36 + 12 = 48
and go on...
The pattern for the second is one is that you have to multiply by 2. Example:
3 × 2 = 6
6 × 2 = 12
12 × 2 = 24
Part 2:
You would do the same steps shown above. Add twelve to the following number which is 60. So, 60 + 12 = 72.
You would also need to multiply 2 and 96 since its the given number. 96 × 2 =192.
Part 3:
The first sequence is an arithmetic sequence because the number 12 is constantly being added.
The second sequence is a geometric sequence because 2 is constantly being multiplied.
I hope this helps!
Answer:
value of expression = 12
Step-by-step explanation:
[(-10+2)-1]+(2+3)
= [(8)-1]+(5) ∵according to PEMDAS, we first solve the Parenthesis
= (7)+(5)
= 12
20 and 7 Because 4x5 = 20
