C: 62.8
If this helped please give thanks and maybe mark brainliest! Thanks!
Answer:
62.8 mm
Step-by-step explanation:
C= 2 X pi X r = 2 X pi X 10mm = 20 pi mm = around 62.8 mm
r = d/2 = 20mm/2 = 10mm
5t - 2t = 84 - 54
3t = 30
t = 30/3
t = 10.
150 units^2
A=6a2=6·52=150
inaccurate
3 less than would be x-3, but 3-x would be 3 more
