suter [353]
Since the Power is directly proportional to the velocity, their ratio \frac{P}{v^{3} } is constant.

<span>Therefore </span>\frac{500}{ 10^{3} } = \frac{x}{ 12^{3} } which is a proportion:

500 : 1000 = x : 1728

that can be easily solved:

x = (500×1728)/1000 = 864kW

A circle with a radius of 10 inches is placed inside a square with a side length of 20 inches. Find the probability that a dart
melamori03 [73]

Answer:

The correct answer is last option 78.5%

Step-by-step explanation:

Points to remember

Area of circle = πr²

Where r is the radius of circle

Area of square = a²

Where 'a' is the side length of square

<u>To find the area of circle</u>

Here r = 10 cinches

Area =  πr²

 =  3.14 * 10²

 = 3.14 * 100 = 314

<u>To find the area of square</u>

Here a = 20 inches

Area = a²

 = 20²

 = 400

<u>To find the probability percentage</u>

Probability = area of circle/Area of square

 = (314/400)*100

 78.5 %
