The radius of the circle is increasing at a rate of 2 meters per minute and the sides of the square are increasing at a rate of

Lunna [17]

Answer:

Change in area=24 $\pi$ -48

Step-by-step explanation:

Let s will be the side of square and r will be the radius of circle.

Then two given conditions are

1)dr/dt=2 m/s

2)ds/dt=1 m/s

Area enclosed=(Area of square)-(Area of circle)

Area of square= $s^{2}$

Area of circle= $\pi r^{2}$

Area enclosed= $(\pi r^{2})-s^{2}$

dA/dt=2 $\pi$ r(dr/dt)-2s(ds/dt)

At s=24,and r=6

dA/dt=2( $\pi$ )(6)(2)-2(24)(1)

Change in area=24 $\pi$ -48

on Serena's 10th birthday her mom was 3 times her age.How old will Serena and her mom be when her mom's age times 0.5 equals Ser

alex41 [277]

When Serena is 10, her mom is 3*10=30. Her mom is 20 years older than Serena.

If her mom's age divided by half is equal to Serena's, then she will be twice as old as Serena.

20 + 20 = 40
20 * 2 = 40

Serena will be 20, her mom will be 40.
