x = 7 is parallel to x = 8
y=8 is perpendicular to x=8
If this is suggesting circumference then you would use the equation pi(d). You can round off pi to 3.14 and substitute in the diameter of the circle in the equation: 3.14(75)=235.5 which then rounded would equal 236. Circumference also refers to if you would cut the circle so that it was a line segment, in meaning the entire measurement of the circle around.
Volume of a cone is pi*r^2*h/3
Volume of cone is approx. 20.9.
Volume of a sphere is 4/3pi*r^3
Volume of sphere is approx. 113.1
113.1 - 20.9 = 92.2 approx.
152 * 4= 608
608+2= 610
If this isnt what you mean then I'm sorry.I guess I just don't understand the question
