Answer:
The general formula for the total surface area of a regular pyramid is T. S. A. =12pl+B where p represents the perimeter of the base, l the slant height and B the area of the base.
Answer:
units.
Step-by-step explanation:
We have been given that two legs of triangle ABC measures 5 units each. We are asked to find the length of the hypotenuse.
We will use Pythagoras theorem to solve for the hypotenuse of triangle ABC.

Substituting our given values in above equation we will get,



Upon taking square root of both sides of our equation we will get,



Therefore, the length of hypotenuse of triangle ABC is
units.
Answer:
Step-by-step explanation:
Sum of all angles of triangle = 180
39 + 102 + x = 180
141 + x = 180
Subtract 141 from both sides
x = 180 - 141
x = 39
Given that population of the city is 280000.
Rate of growth of the population = r = 4.5% = 0.045
We have to find population after 15 years so time
t = 15
We can use growth formula to find the required population which is given by :

Where P= starting population = 280000
r= rate of growth = 0.45
t= time = 15
now plug these values into above formula.




Hence population after 15 years will be approx 73735743.
