I am not looking for an answer just easy steps on how to do this. It would be very helpful Thank you!
18. r = 3 in.
19. d = 15 m
18. r = 3 in.
19. d = 15 m

18. to find the circumference, multiply 3 in. by 2 to get the diameter. then multiply the diameter by pi. (3.14) (the formula is Circumference= pi times diameter
the formula to find the area is A = pi times radius squared.
so you square 3(multiply 3 times 3) and multiply that answer by pi (3.14).
for #19, do the same thing, but for the circumference, you don't multiply by 2, and for the area, you divide by 2 instead.

Circumference = 2*pi*r
Area = pi *( r*r)
pi=3.14159
Area = pi *( r*r)
pi=3.14159
