Replace the CIRCLES by A and the SQUARES by B:
1) A + B = 14 And
2) A - B = 2
Add 1) + 2)
A+B =14
A-B = 2
------ ----
2A+0 = 16 then A = 16/2 = 8. If A = 8, then B = 6
So the CIRCLE = 8 and the SQUARE = 6
Didn't use algebra but Gary would be 3 and Karen would be 13 so in 2 years Gary would be 5 and Karen would be 15 and 5 x 3 = 15 so ya.

Answer:
<em>V = 65.9 cubic millimeters</em>
Step-by-step explanation:
<u>The Volume of a Right Circular Cone</u>
Given a right circular cone of radius r and height h, its volume is calculated as follows:
The cone shown in the image has a radius of r=3 mm and a height of h=7 mm, thus the volume is:
Taking pi as 3.14:
Calculating:
V = 65.9 cubic millimeters
