Respuesta :

Answer:

238.23 meters.

Step-by-step explanation:

STEP 1

Find the circumferences of both circles!

Outer circle:

C = (radius*2)π

C = (52*2)π

C = 104*π

C = 326.725...

C ≈ 326. 73

Inner circle:

C = (radius*2)π

C = (30*2)π

C = 60*π

C = 188.495...

C = 188.50

STEP 2

Find the difference by subtracting.

outer circle - inner circle = difference

326. 73 - 188.50 = 238.23

238.23 meters.
