2% is 2/100, so we have 2/100*7,000,000,000=140,000,000 people with red hair.
Answer:
A
Step-by-step explanation:
To turn a fraction into a percent, you divide the numerator by the denominator.
8 divided by 9 = .8 repeated
To turn it into a percent, you move the decimal to the right 2 spaces.
.8 turns into 88.8 repeated
Then you round to the nearest hundredth
88.8 repeated rounds to 88.89.
The significant components, the radius and the height, are in inches and feet respectively, you'd need to convert them both to the same unit, whichever it may be, meters or feet or inches or millimeters, so long is the same, then use the volume of a cylinder equation to get it.
You have to multiply whats outside the parenthesis with everything that is inside, so
Multiplication of same bases we sum the exponents
Alternative B.
