Answer:
7
Step-by-step explanation:
An easy way to find any percentage of a number is to multiply with decimals. To do this you have to first convert the percentage to a decimal. Do this by moving the decimal point in the percentage 2 places to the left. This means that 2.0% becomes 0.02. Then, multiply this decimal by the whole number. So, 0.02*350. This equals 7, which is 2% of 350.
This same trick will work with any problem. For example 38% of 435 is the same as 0.38*435, which equals 165.3.
Solve:-
Write it down again:-
3 · 3 · x · x · x · x
We will write it like this:-
3 · 3 · x³

Its 50. Because circumference is 314. Divide that by 3.14 and you get the diameter. Divide by another 2 and you get 50.
This is a puzzling question, so my answer is not 100%, but:
"<span>8 x^2 - 2 x + 2" is what I got. </span>
