Answer:

y=2√3, or 3.46410161513

Step-by-step explanation:

The smaller triangle is a right isosceles triangle, so the other side is also √2. To figure out it’s hypotenuse, you can use the Pythagorean theorem.

√2²+√2²=c²

2+2=c²

4=c²

√4=c

c=2

Now that we know that value, we can look at the bigger triangle. It is a 30-60-90 triangle, which has special properties.

Y would equal the two of the base times the square root of three.

y=2√3, or 3.46410161513

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
