<span>So we want to know the volume V of a cone with a height h=7 mm and of radius r=3 mm rounded to the nearest hundreth. We need the formula for the volume of a cone: V=(1/3)*pi*r^2*h. Now we simply input the numbers and get: V=65.94 mm^2 and that is rounded to the first hundreth.</span>
Cross multiply X×4=3×1
4x=3
X= 3/4
the constant of variation or namely its slope will be
