Answer 2

HI!!

Answer 3

ircumference equals π times diameter. So to get the diameter, you divide circumference by π. So the diameter is 13 feet. 42/π=13. (π equals approximately 3.141)

Answer 4

the circumference of a circle is pi times the diameter, i.e \[C=\pi \times D\]

Answer 5

you are told the circumference, so you want to divide \[D=\frac{D}{\pi}\]
