A towns population went from 25800 to 42600 in 15 years. What was the percent of change
Answers
Answer:
Step-by-step explanation:
The percent of change respect a reference value is given by the following formula:
On this case the initial value is 25800 and the final value 42600. So we can replace into the formula and we got:
So then the increase respect the initial value is 65.116%, and makes sense since:
To find this answer, I divided 42,600 by 25,800 and got 1.651162791... I then multiplied it by 100 to convert it into a percent and got 165.1162791...%
The "..." after the number means that the numbers continue to go on but are essentially unnecessary.
In conclusion, when you multiply 1.651162791... you get 42,600.

B. r = V /πh
C. r = 3V/ πh
D. r = ± /V πh
Answers
V = pi*r^2*h/3
so we have to solve for radius:
r = √(3V/pi*h)
that is how to get the radius.

Answer:
b = 12
Step-by-step explanation:
The mistake Megan has made is that she has squared the lengths and then added it instead of taking away the squared length's. The method she used was to work out the hypotenuse, so the correct method would be as follows:
a² + b² = c²
→ Substitute in the values
5² + b² = 13²
→ Simplify the equation
25 + b² = 169
→ Minus 25 from both sides to isolate b²
b² = 144
→ Square root both sides to find the value of b
b = 12

Answer:
The surface area of a solid object is a measure of the total area that the surface of the object occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with flat polygonal faces), for which the surface area is the sum of the areas of its faces. Smooth surfaces, such as a sphere, are assigned surface area using their representation as parametric surfaces. This definition of surface area is based on methods of infinitesimal calculus and involves partial derivatives and double integration.
