Answer:
The cup can hold <u>235.5 cubic cm</u> of popcorn.
Step-by-step explanation:
Given:
A cone shaped popcorn cup has a radius of 5 cm and a height of 9cm.
Use 3.14 as an approximation for pi.
Now, to find cubic cm of popcorn the cup can hold.
Radius ( r ) = 5 cm.
Height ( h ) = 9 cm.
π = 3.14 ( as per question ).
So, to get the cubic cm of popcorn the cup can hold we put formula of volume:




Therefore, the cup can hold 235.5 cubic cm of popcorn.

Answer:
p = 497 ( to the nearest whole number)
Step-by-step explanation:
In order to do this calculation, we will apply the principle of accounting, where a certain amount is compounded periodically and yielding a future value. Compound interest is used because the percentage growth rate is added on the new amount gotten each year, and not on the first or original amount.
Hence:
FV = PV × 
where FV = future value = population in 2020 = 810
PV = present value = population in 2010 = p
r = percentage growth rate in decimal = 5% = 5/100 = 0.05
n = growth rate period per year = once = 1
t = time in years = 2010 to 2020 = 10 years
∴ 
(dividing both sides by 1.6289)
p = 810 ÷ 1.6289 = 497.2 = 497 (to the nearest whole number)
∴ population in 2010 = 497
