Answer:
we are going to use the formula...
V=πr2h
Step-by-step explanation:
so
V = (3.14) 4x4 (9)
V = (3.14) 16 x 9
V = 3.14 x 144
V = 452.16
Hence, the third or C

Or, if that hyphen between the lower index and 3 is actually a negative sign, then the sum is -189.
6(x^2-1)(6x-1/6(x+1))
On factoring (x^2-1)=(x+1)(x-1)
= 6(x-1)(x+1)(6x-1/6(x+1))
Cancelling (x+1) from numerator and denominator we get,
= 6(x-1)(6x-1)/6
Cancelling 6 we get,
= (x-1)(6x-1)
