The diameter of circular garden is 18 feet. what is the approximate area of the garden?

A. 50 square feet

B. 100 square feet

C. 254.34 square feet

D. 803 square feet

Option C, 254.34 square feet

Step-by-step explanation:

Area of a circle formula:  A = πr^2

Step 1:  Find the radius

Since they give us the diameter, we need to find the radius.

18/2

9 = radius

Step 2:  Plug into the formula

A = π(9)^2

A = 81π

A = 254.34 square feet

 Option C, 254.34 square feet

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
