babunello [35]

9514 1404 393

Answer:

  216.66 yd²

Step-by-step explanation:

One way to find the area of a ring like this is to multiply its centerline length by the width of the ring.

Here, the diameter of the circle that is the centerline of the ring is 23 yd. The circumference of that circle is ...

  C = πd = 3.14(23 yd) = 72.22 yd

Then the ring area is ...

  (72.22 yd)(3 yd) = 216.66 yd² . . . area of shaded region

Each side of a square is increasing at a rate of 2 cm/s. at what rate is the area of the square increasing when the area of the
faltersainse [42]
Let x(t) =  the length of a side of the square (cm) at time t (s).
The rate of change of x is given as
\frac{dx}{dt} =2 \,  \frac{cm}{s}

The area (cm²) at time t is 
A = x²

The rate of change of the area with respect to time is
\frac{dA}{dt} = \frac{dA}{dx}  \frac{dx}{dt} =2 \frac{dA}{dx} =2(2x)=4x \,  \frac{cm^{2}}{s}

When A = 9 cm², then x = √9 = 3cm. Hence obtain
\frac{dA}{dt} = 4(3) = 12 \,  \frac{cm^{2}}{s}

Answer: 12 cm²/s
