Answer:
circumference = 2πr
diameter = 2r
Step-by-step explanation:
2πr = 2r + 16.8
2πr - 2r = 16.8
2r(π - 1) = 16.8
r(22/7 - 1) = 8.4
15r/7 = 8.4 => r = 58.8/15
r = 3.92 cm Ans

Answer:
Step-by-step explanation:
→ circumference = 2πr
→ diameter = 2r
→ 2πr = 2r + 16.8
→ 2πr - 2r = 16.8
→ 2r(π - 1) = 16.8
→ r(22/7 - 1) = 8.4
→ 15r/7 = 8.4
=> r = 58.8/15
→ r = 3.92 cm
