Step-by-step explanation:
Volume =pir^h
V1=pi r1^h
V2=pir2^2h
Now,V1/V2=r1^2/r2^2
v1/v2=r1^2/(1.05)^2 ((r2=r1+5/100r1)
v1/v2=1/1.1025
v1/v2=0.907
(v1/v2-1)=0.0907×100%
(v1-v2)/v2=9.07%
increase in volume is 9.07%
Answer:
15,000 people
Step-by-step explanation:
This is the question of ratio, it is the quantitative relationship of two number.
In this survey a ratio of 66 people out of 110 is defined as living in apartment, based on this ratio we can estimate the total numbers of people living in apartments.
Total population of the town = 25,000 people
Ratio of people living in apartment = 66 / 110 = 0.6
Town people living in apartment = 25,000 x 0.6 = 15,000 peoples

Step-by-step explanation:
- 3000
After 5 years, value doubles.
Hence after 5 years, value is 250 x 2 = 500
After another 5 years, value doubles.
500 x 2 = 1000
Ans: $1000
Method 2, using function given.
v(10) = 250 x 2(10/5) = $1000
