Answer:
1900.66
I don't see the answer there in the list of options, maybe I got the values wrong...
Step-by-step explanation:
This pic is blurry so I'm going to assume the numbers given are 3, 8, and 11.
Volume of larger cylinder:
π*r^2*h
(π)(64)(11) = 704π
Volume of smaller cylinder:
π*r^2*h
(π)(9)(11) = 99π
Subtract the two answers together:
704π - 99π = 605π
Simplify:
605π ≈ 1900.66
Move a2 to the left side of the equation so you have c2-a2. then divide by 2 to get b by itself. you are left with c2-a2 all over 2. the 2s will cancel and you'll be left with c-a=b
