Answer:
15
Step-by-step explanation:
Given that a1 = 6
an = 3 + 2(an-1),
Substitute n = 2 into the formula
a2 = 3 + 2(a1)
a2 = 3 + 2(6)
a2 = 3+12
a2 = 15
Hence the second term of the sequence is 15
Note that, if the two solids are similar with a scale factor of x, then the ratio of their areas would be
and the ratio of their volumes would be
.
In this case, the ratio of the two similar solids is 3:14. So the ratio of their areas would be
and,
the ratio of their volumes would be
Thus, the answer is 9 : 196 and 27 : 2744.
THE VALUE OF 9 IN 495,123 IS 10000 <span>TIMES THE VALUE OF 9 IN 63,129</span>
