Area of a Circle: The area of a circle is the amount of space the circle takes up. To compute the area of a circle, we use the formula a=πr^2 where r is the radius of the circle.
Radius: The radius of a circle is the distance from the center of the circle to any point on the circle.
Answer:
=2w2+9w−35
Step-by-step explanation:
(2w+−5)(w+7)
(2w)(w)+(2w)(7)+(−5)(w)+(−5)(7)
2w2+14w−5w−35
2w2+9w−35
Answer:
r
Step-by-step explanation:
10r - 9r = r
Answer: Approximately 8.78 million
Step-by-step explanation:
Since the population is growing at a rate of 3.1% each year, that is synonymous to percentage increase
%increase = increase/initial population × 100
Or
(3.1 + 100)/100 × initial population = 9.05 million
= 1.031 × initial population = 9.05 million
Initial population = 9.05million/1.031
Initial population = 8.78 million
