Volume of Spheres
Oliga [24]
It’s simple. The volume of a sphere is V=4/3πr^3.. so you will convert the mm to m okay?? 10mm=1cm .. so do your conversion from here then when you get the radius then you will substitute it into the volume where r is the radius.. so for the first one l changed mm to cm so.. radius is 4cm then l substitute it into the formula so l got 270 after rounding it to the nearest tenth.. pi=22/7 bear in mind. So do the same for the other one

Determine if y=-2x-7 and -y=2x+13 are parallel, perpendicular, coincide or none of these
Goryan [66]
If you move the negative on the left side of the second equation over to the right side, then we can see that the equation is equivalent to y={-2x} - 13.

Remember that an equation y = mx + b represents a line with slope m and y-intercept b. Since both equations given have a slope of -2, but have different y-intercepts, they are parallel.
