A stone is dropped into a lake, creating a circular ripple that travels outward at a speed of 35 cm/s.

sashaice [31]

Answer:

The radius r of this circle as a function of the time t :

$r(t)=35\times t$

Step-by-step explanation:

Speed of the circular ripple = S = 35 cm/s

Radius of the ripple at time t = r

$Speed=\frac{Distance}{Time}$

$35cm/s=\frac{r}{t}$

$r=35 cm/s \times t$

The radius r of this circle as a function of the time t :

$r(t)=35\times t$
