Surface area of cone is a sum of surface of its base and surface of its mantle.
Surface of its base is a circle which surface we will calculate like this:
Sb = pi*r^2 where r is d/2
Sb = 201m^2
Surface of mantle we calculate by:
Sm = pi*l*r where l is length of side of cone.
l =

= 25.3
Sm = 635.8m^2
Total suface is:
Sb + Sm = 836.8m^2
Answer:
219 employees
Step-by-step explanation:
3% of decreasing rate of employees per year is calculated thus:



In 9 years,


Therefore, the number of employees for a certain company where decreasing rate of employees is 3% and continued to decrease for 9 years; and 810 employees are currently working is 219 employees. By implication, 810 + 219 = 1029 employees were working in the company 9 years ago.
Answer:
A. The price would be 24 because 28-4 dollars is 24
B. How much a cost altogether and the fact that he has two kids
C. You can take the total of the price of all their tickets combined to subtract 24 and you would get 52 so so I slice and a half in and you have the answer
D 26 dollars each
E. 76-24=52 52/2=26
