Answer:
185553.7 feet^3
Step-by-step explanation:
That's geometric sequence
T7 = T5*r^2 = T5+1920
r = 2, so
4*T5 = T5 + 1920
3T5 = 1920
T5 = 640
640 = 2^4 * 40
So, a=40 and the sequence is
40 80 160 320 640 1280 2560 5120 10240 20480 40960 ...
Note that 2560 = 640 + 1920

Answer:
The first answer choice: 15 cm x 3.14 cm x 2cm^2 = 188.4 cm^3
Step-by-step explanation:
Formula:
V=πr^2h
radius=2
height=15
V=π(2)^2*15
π(4)*15
4*15=60
60π
π=3.14
60(3.14)
188.4
Since its volume you have to cube it
188.4 cm^3
For the answer to the question i<span>dentify a3 of this sequence: 0.25, 0.5, 0.75, 1, 1.25, 1.5
a3 =
