Answer: 28.27
explanation: A circle of radius = 3 or diameter = 6 or circumference = 18.85 centimeters has an area of 28.27 square centimeters.
<span>The biggest out of the two possible answers is 0.45. 2/5 in decimal form is 0.4, or in percentage form becomes 40%. However, if 0.45 is changed into a fraction, it becomes 9/20 in its smallest form, which is difficult to compare. If we consider 0.45 as a percentage, however, it obviously becomes 45%, which is bigger than 40% so we can confirm that 0.45 is larger than 2/5.</span>
Answer: There are 12 white and blue cars more than silver and red cars
Number of white cars: n1=25
Number of blue cars: n2=17
Number of white and blue cars: n3=n1+n2=25+17→n3=42
Number of silver cars: n4=21
Number of red cars: n5=9
Number of silver and red cars: n6=n4+n5=21+9→n6=30
How many more white and blue cars are there than silver and red cars?
n=?
n=n3-n6=42-30→n=12
Answer: There are 12 white and blue cars more than silver and red cars.
To help you you should find a common denominator and then the fraction that has lower numbers is bigger
