100% - 25% = 75%
so, if 18.95 is the 100%, how much is the 75% of that?
solve for "x".
In 2014, the population of Hong Kong was estimated to be approximately 7,112,688 people. The city covers an area of approximately 426.25 square miles.
The number of people = 7,112,688
City area = 426.25 square miles
The population density =
=
= 16686.65806 people per square mile
The population density of Hong Kong in 2014 is 16687.
9 times 8 times 7 will give you 504
8 2/5 = 8.4 is your answer.
Answer: B. 254.34 cm^2
Step-by-step explanation:
The area of a circle is pi times the radius squared.
Using the diameter we have to find the radius.
The diameter is two times the radius meaning that the radius is half the diameter.
18/ 2 = 9
The radius will be 9 cm
Now using the formula v= pi * r^2 , input the value for pie and the radius and solve for v the volume
v = 3.14 * 9^2
v= 3.14 * 81
v = 254.34 cm^2
