I'll tell you how to find the answers and just use the give angle measure to solve.
9) angle 11 = angle 14
10) angle 9 + angle 15 = 180
11) angle 10 = angle 3
12) angle 7 = angle 14
To answer this, you should "subtract" x+y=7 from 3x+y=45.
What is left is 2x=38, where x then equals 19.
Plug this value into any of the equations (I will choose x+y=7 for simplicity).
19+y=7, y=-12
Check this answer by plugging it into the other equation.
3(19) + (-12) =45
45=45 so it is correct
X=19 and Y=-12
Volume of sphere = 4/3πr<span>³
14.14 = 4/3 *22/7 *r</span>³
14.14 * 3/4 * 7/22 = r³
∛3.37 =r
1.499 = r
so 1.5 mm is the radius
