Answer:

$\large\boxed{\sf \ \ \ 404,699 \ \ \ }$

Step-by-step explanation:

Hello,

At the beginning the population is 240,000

After 1 year the population will be

240,000*(1+7.75%)=240,000*1.0775

After n years the population will be

$240,000\cdot1.0775^n$

So after 7 years the population will be

$240,000\cdot1.0775^7=404699.058...$

So rounded to the nearest whole number gives 404,699

Hope this helps

Please help me question is in the picture

Answer:

172.70 sq. ft.

Step-by-step explanation:

The surface area of a circular cone is

$SA = \pi r^{2} + \pi rl$ r = radius of base l = slant height

r = 4.4 and l = 8.1

$SA = 3.14 (4.4^{2}) + 3.14(4.4)(8.1)\\$

SA = 3.14(19.36) + 111.9096

= 60.7904 + 111.9096

= 172.70 sq. ft.
