Answer choices :
a. 113 in.
b. 340 in.
c. 250 in.
d. 226 in.

b. 340 in.

Step-by-step explanation:

The area of a cylinder is * *h, so you can substitute the values you have in.

You would get * 3 * 3 * 12 = 108 *

Since you are estimating, use 3.14 for pi.

Then, you do 108 * 3.14 and you get 339.12, which is closest to answer choice b, 340 inches.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
