Answer:

The radius of the oil spill growing at 2 feet per minute

Step-by-step explanation:

Area of a circle is

$A=\pi r^2$

Differentiating A with respect to r,

$\dfrac{dA}{dr} = 2\pi r$

When $A=100\pi$ ,

$100\pi = \pi r^2$

$r = 10$

The rate of growth of the spill is

$\dfrac{dA}{dt} = 40\pi$

This is equivalent to

$\dfrac{dA}{dt} = \dfrac{dA}{dr} \times \dfrac{dr}{dt}$

$\dfrac{dr}{dt} = \dfrac{dA}{dt}/\dfrac{dA}{dr} = \dfrac{40\pi}{2\pi r} = \dfrac{20}{r}$

$\dfrac{dr}{dt} = \dfrac{20}{10} = 2$

My name is Ann [436]

Answer:

22.4

Step-by-step explanation:

A car is driving down the road and goes 500 miles in 10 hours.

So,

d = 500 miles = 804672 metres

t = 10 hours = 36000 minutes

∴ v = d ÷ t

v = 804672 ÷ 36000

v = 22.352

∴ v = 22.4 m/s

Thus, His Velociy was 22.4 m/s
