How do you find the circumference of a circle if the diameter is 4

if your looking for an answer it’s c= 12.57

Step-by-step explanation:

other answer is correct. i had used the radius of the radius somehow. a website:

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
