FD= 16
Step-by-step explanation:
Answer:
C) 
Step-by-step explanation:
Given Equations:
A) 
B) 
In order to eliminate 
we need to multiply 
to equation B and add it to A.
Multiplying to B.
⇒ 
⇒ 
⇒ 
Adding it equation A.
+ 
We get 
Thus is eliminated.
So, the expression used to eliminate is:
The equation for area is pi times r^2.
Here the diameter is 12, so the radius would be 6. (Diameter is twice the radius.)
Substituted this is pi times 6^2.
The area for the picnic table is about 113.097
______________________________________
The equation for circumference is 2 times pi times r.
Substitute, 2 times pi times 6.
The circumference is about 37.699
