Answer:
Volume = 3140 unit³
Step-by-step explanation:
If radius of a sphere is 10 unit
Volume of sphere = pi r³
Where pi = 3.14
Volume = 3.14 × 10³
Volume = 3.14 × 1000
Volume = 3140 unit³

Answer as a fraction = 1/720
Answer in decimal form (approximate) = 0.001388
Answer in percent form (approximate) = 0.1388%
========================================================
Explanation:
Let A = 1 to indicate the number of ways to get the names to line up in alphabetical order.
There are B = 6*5*4*3*2*1 = 720 different ways to arrange the six people. Notice how I started at 6 and counted my way down to 1, multiplying all along the way. This can be shortened to factorial notation to say 6! = 720. Or you could use the nPr permutation formula to get the same result (use n = 6 and r = 6).
Once you have the values of A and B, we form the fraction A/B = 1/720 which is the probability of getting the names in alphabetical order.
If you need the answer in decimal form, then use your calculator to find
1/720 = 0.001388
which converts over to 0.1388%
Answer:
Y=150,000*(1.1)*
Step-by-step explanation
As Every year the rate of increase is 10% therefore the rate 1+10%=1.1, and X is number of years. So, (1.1)*, and after x years to get the correct value you can multiply, y=150,000*(1.1)*
