A new crop circle has appeared in Cool Town. It is a rather simple one. It consists of two concentric circles. The largest (outer) circle has a radius of fifty-two meters and the inner circle has a radius of thirty meters. What is the difference between the circumferences of the two circles?

138.16

Step-by-step explanation:

first you find the circumference of both of them. the big one is 52*2 *pi 52*2 is 104 then you multiply by pi 326.56

for the second circle you do 30*2*pi and get 188.4 then you subtract them and get 138.16

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
