Please Help You have twice as many nickels as pennies. you have $1.10. How many of each coin do you have? Solve each problem using a system of equations.

$1.10:

divide by 2 you get $0.55 divide that by 5 and you get $0.11 so you got 11 nickels and how many pennies...

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
