Area of a square = length²
A = x²
16 = x²; x = 4
dA/dx = 2x cm²/s
dx/dt = 6 cm/s
Using chain rule:
dA/dt = dA/dx * dx/dt
dA/dt = 2x * 6
dA/dt = 12x
At x = 4,
dA/dt = 12(4) = 48 cm²/s
Greater than.
yards are a larger unit of measurement, so to convert it there are more millimeters to count the same amount of space.
Given the radius is, r = 16 in,
The expression for the circumference of a circle is,

Therefore, we have,

Thus, the circumference of the circle is 100.48 in.
