When 2/3 is added to a certain number, the sum is 3 greater than twice the number. part 1: set up an equation using n to represent the number. part 2: solve the equation in part 1 for n.?

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

step-by-step explanation:

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5
