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
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

The area (cm²) at time t is
A = x²
The rate of change of the area with respect to time is

When A = 9 cm², then x = √9 = 3cm. Hence obtain

Answer: 12 cm²/s
Answer:
A

Answer:
12u-6
Step-by-step explanation:
Distributive Property
(2 − 4u)(–3)
-3*2 + -4u*-3
-6+12u
12u-6
