Ksenya-84 [330]

For this case we have the following data:

700 rabbits that represent 500% of the population of last year. So, to obtain the rabbit population of last year, we developed a rule of three:

700 -----------> 500%

x ---------------> 100%

Where x represents the rabbit population of last year.

Clearing x we have:

x = \frac{ 100 * 700}{500}

x = 140 rabbits

In this way, last year there was a population of 140 rabbits.

Answer:

140 rabbits

The radius of a circle of area a and circumference c is doubled. find the new area of the circle in terms of
maksim [4K]
By definition, the circumference of a circle is:
 c = 2 * pi * r&#10;
 The area of a circle is:
 a = pi * r ^ 2&#10;
 Where,
 r: radius of the circle.
 When the radius is double, then the new area is:
 A = \pi*(2r)^2&#10;
 Rewriting we have:
 A = 4 * \pi * r ^ 2&#10;
 In terms of a we have:
 A = 4 * a
 Answer:
 
The new area of the circle in terms of a is:
 
A = 4 * a
