Find the diameter of a circle with a circumference of 15.7 meters. Use 3.14 for π.

5m

Step-by-step explanation:

So to find circumference you multiply the diameter by pi.

To find the diameter you divide the circumference by 3.14.

15.7/3.14=5

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
