_______________________________
r = 84 cm
π = 22/7
C = 2πr
C = 2 . 22/7 . 84
C = 44 . 12
C = 528 cm
≈ 528cm
Explanation:
The formula is pi multiplied by the diameter. So you multiply the radius (84) by two times. Next, you multiply 22/7 by the diameter and you will received 528cm. I hope this answers your question.
