1 answer:
Answer:
A. 31.4 feet
Step-by-step explanation:
The formula for circumference is given by

C = pi * 10
pi is approximately 3.14
C = 3.14* 10
C = 31.4 ft

Answer:
=2xy^3x(xy-3)
Step-by-step explanation:
2x^2y4-6xy^3
=2xy^3x(xy-3)
=2xy^3x(xy-3)
Answer:
0(x) + BY=c
0 + By = c
By = c
divide both sides by BY
BY/by = c/By
= c/by
