The answer to this question will be C
Answer:
c. f(n) = (n+1)^2 + 2
Step-by-step explanation:
It is c. because...
f(n) = (1+1)^2 + 2
2^2 + 2
4 + 2 = 6 (first term)
f(n) = (2+1)^2 + 2
3^2 + 2
9 + 2 = 11 (second term)
f(n) = (3+1)^2 + 2
4^2 + 2
16 + 2 = 18 (third term)
C or 2 and 8
Thanks for the chance for extra points
Circumfernce=2pir
Vcylinder=lpir^2
so what you do is take circumference adnd solvefor r, then input that for r in Volume and solve for legnth
C=2pir
C/(2pi)=r
input
V=lpir^2
V=lpi(C/2pi)^2
V=lpi(c^2/(4pi^2))
V=l(c^2/4pi)
multiply both sides by (4pi)/(c^2) to clear fractio
(4piV)/(C^2)=legnth
basically if you know volume and circumference
legnth=(4pi tmes volume)/(circumference^2)
Uh would it be 7 x 2 + x = 39 Im not that good at math but I think thats its
