Therefore, we can write the two quantities as fractions of twenty:
14/20 and 6/20
A percentage is "per-cent", i.e. per 100, therefore a fraction of 100. To make this denominator a fraction of 100 we multiply it by 5 (20 x 5 = 100), and because what we do to the bottom of the fraction we must do to the top, we multiply each numerator by 5:
The area is approximately 1256.64 The circumference is approximately 125.66
Step-by-step explanation:
This is because to find the area of a circle you square the radius and multiply by Pi. To find circumference, you can multiply the Diameter (twice radius) by Pi.
Justin is <em>not </em>speeding because there is 1.609 km in a mile. So if you compare it to 70 km/h to 50 mi/h it would 70 km and 43.50 miles per hour. So like I said, no he is not because he is going below 50 mi/h.
