Answer:
- 3, 9, 25
Step-by-step explanation:
To find the required terms of the sequence substitute n = 2, 5, 9 into the given rule, that is
= - 7 + (2 - 1)4 = - 7 + (1 × 4) = - 7 + 4 = - 3
= - 7 + (5 - 1)4 = - 7 + (4 × 4) = - 7 + 16 = 9
= - 7 + (9 - 1)4 = - 7 + (8 × 4) = - 7 + 32 = 25
Lets get started :)
We need to find the radius of the larger cylinder
V =
r²h
960 =r²(16)
60 =
r =
r ≈ 4.27 cm
The ratio of the bigger cylinder to smaller is:
16 : 4
Therefore, the big cylinder is 4 times bigger than the small cylinder
= r
r = 1.09 cm (radius of small cyclinder)
V (small cylinder) =(1.09)²(4)
= 15 cm³
Your answer will be C. 15 cm³
