The area of circular garden is 615.44 feet2. What is the circumference of the garden? (Use 3.14 for .)
A.
205.15 feet
B.
87.92 feet
C.
43.96 feet
D.
307.72 feet

87.92 ft

Step-by-step explanation:

Area of a circle = pi*r^2.                                    A

If the area is given, then the radius is r = √  

                                                                           pi

circumference of a circle = 2*pi*r.  We use the expression for r found above:

                                                          615.44

Circumference of garden = 2*pi* √

                                                              pi

Substituting 3.14 for pi, we get:  

                                                           615.44

Circumference of garden = 6.28* √ = 6.28*14 = 87.92 ft

                                                              3.14

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
