Answer 2

hint:
the length of the edge of the flower garden is:
\[\large L = 2 \times \pi \times R\]
where:
R is the radius, namely:
\[\large R = \frac{D}{2}\]
and D is the diameter

Answer 3

edge means circumference of the circle here

Answer 4

L=2*3.14*15?

Answer 5

no,
L=2*3.14*7.5
since the radius is:
R = 15/2=7.5 feet

Answer 6

oh gotchya! k now what next step? I got 47.1 for the above part

Answer 7

ok!

Answer 8

now, we have to multiply that length by 3 1/2

Answer 9

okay and that gave me 164.85
