Answer: pretty sure -7
Step-by-step explanation:
Given:
The diameter of cylinder is 6 in and the height of the cylinder is 8 in.
The dimensions of the cuboid are 15 in by 9 in by 9 in.
To find:
The volume of the composite figure.
Solution:
Volume of a cuboid is:
So, the volume of the cuboid is 1215 cubic inches.
The diameter of cylinder is 6 in. So, the radius of the cylinder is:
Volume of a cylinder is:
Where, r is the radius and h is the height.
Substituting 
, we get
The volume of the cylinder is 226.08 cubic inches.
Now, the volume of the composite figure is:
Therefore, the volume of the composite figure is 1441.08 cubic inches.
The interest rate needed to double the investment in 18 years is 6%.
<h3>What is the interest rate?</h3>
Interest earned is a function of the amount invested, interest rate and time. The future value of the investment is to be $6000 (3000 x 2). Interest earned would be $3000 (6000 - 3000)
Interest rate = interest earned / (amount invested x time )
$3000 / ($3000 x 18) = 6%

Please note that if you mult. 243 by 2/3, you get 162.
If you mult. 162 by 2/3, you get 108.
If you mult. 108 by 2/3, you get 72.
We can then safely conclude that the common ratio is 2/3.
Our last given set member was 72.
Mult. this by 2/3 to get the 5th member: 48.
Mult. this 48 by 2/3 to get the 6th member: 32.
Mult. this 32 by 2/3 to get the 7th and last desired member: 21 1/3
Answer:
What factors do the numbers 12 and 18 have in common?
O D. 1, 2, 3, 6
Step-by-step explanation:
12 = 1, 2, 3, 4, 6, 12
18 = 1, 2, 3, 6, 9, 18
factors do the numbers 12 and 18 have in common = 1, 2, 3, 6
