Answer:
c=−3 or c=7
Step-by-step explanation:
Step 1: Cross-multiply.
c/3= 7/c−4
c*(c−4)=(7)*(3)
c2−4c=21
Step 2: Subtract 21 from both sides.
c2−4c−21=21−21
c2−4c−21=0
Step 3: Factor left side of equation.
(c+3)(c−7)=0
Step 4: Set factors equal to 0.
c+3=0 or c−7=0
c=−3 or c=7
Answer: 122.17
Step-by-step explanation:
You have to use the formula: A=πr(r+h2+r2)
If the diameter is 6 then the radius is 3 and h is 9.5
