The cone in the figure below has a volume of 722 cubic centimeters and a height of 6

azamat

Answer:

r = 10.72 cm

Step-by-step explanation:

h = 6 cm

Volume of cone = 722 cubic cm

$\frac{1}{3}\pi r^{2}h=722\\\\\frac{1}{3}*3.14*r^{2}*6=722\\\\r^{2}=\frac{722*3}{3.14*6}\\\\r^{2}=114.97\\\\r = \sqrt{114.97}\\\\r = 10.72$

How many minutes he does arm routine and abdominal routine

AlekseyPX

Let $x$ be the amount of time it takes to perform an arm routine and $y$ be the amount of time it takes to perform an abdominal routine. We see:

$4x+y=70$
$4x+2y=100$

Subtracting the second equation from the first gives $y=30$ . Substituting gives $4x+30=70$ , so $4x=40$ and $x=10$ .

Thus, an arm routine takes ten minutes and an abdominal routine takes thirty minutes.
