Answer: a= 16
Step-by-step explanation:
We have the following expression:

To find the value of the coefficient "a" you must use the distributive property to multiply the expression:
 
until you transform it to the form:

Then we have

Therefore the value of a in the polynomial is 16

Answer:
1203.6 ---- the six is recurring ( .666666...)
Step-by-step explanation:
volume of hemisphere=  x 3.14 x r^3
 x 3.14 x r^3
volume of cylinder= 3.14 x r^3 x h 
1. Volume of hemisphere= 2/3 x 3.14 x 5^3 = 261.6 recurring
2. volume of cylinder = 3.14 x 5^2 x12 = 942
3. add the two together -----------> 1203.6
