Answer:
110.5π
Step-by-step explanation:
The formula for the area of a circle is π r ²
R stands for radius. So, the radius is 10.5, you have to square it meaning 10.5 * 10.5.
110.5 and now you multiply by π so the answer is 110.5π

Answer:
The rate of change of weekly demand is -1/6.
Step-by-step explanation:
It is given that the quantity demanded weekly of the Super Titan radial tires is related to its unit price by the equation
where p is measured in dollars and x is measured in units of a thousand.
We need to find the rate of change in weekly demand, when x=6, p=288 and .
Subtract p from both sides.
Differential with respect to t.
Divide both sides by 2x.
Substitute x=6 and in the above equation.
Rate of change in weekly demand is 0 (approximate to the nearest tire). It dose not make any sense.
Therefore, the rate of change of weekly demand is -1/6.
Answer:
6 cars per hour
Step-by-step explanation:
The rate can be expressed several ways. One of them is "cars per hour". To find that rate, divide cars by hours:
(24 cars)/(4 hours) = 6 cars/hour
__
If 6 cars were washed in 60 minutes, another way to express the rate is ...
(60 minutes)/(6 cars) = 10 minutes/car
__
When you ask "what is the rate?", you need to be specific as to the rate you're interested in. Different expressions of the rate are useful for different purposes.
