Answer:
56.55
Step-by-step explanation:
C=2πr=2·π·9≈56.54867cm
Formula for the circumference of a circle:
C = 2πr (C = circumference π(pi) = 3.14..... r = radius)
You know:
r = 9 cm
π = 3.14 So substitute/plug it into the equation
C = 2πr
C = 2(3.14)(9)
C = 56.52 cm

i need help with this too
Step-by-step explanation:
lmk if you get the answer
B) I think because it's 8 by 10
The answer is 10 thousand
If the radius is 25, the diameter is 50.
Use C = (3.14)(50)
C = 157
No need round off to the nearest tenth.
