A farmer is putting up a fence for her animals. She orginally had the fence enclosing a square was 18ft by 18ft. Suppose she uses the same amount of fencing to enclose a circular area. What is the area of the circle?

Answers

Answer 1

Answer: First look: More than 324 square feet :)
Now, $l=2\pi*r$ which means that $r=(l)/(2\pi)$ . But l is the original perimeter, 4 times the side of the square, that is, 72 ft. So, $r=(72)/(2\pi)=(36)/(\pi)$
Now, the area of that circle is $A=\pi*r^2=\pi*(1296)/(\pi^2)=(1296)/(\pi)$ , which is about 412.5 square feet. It's true, that's more (that's the most you can actually get with that amount of fence :) )

9) In one year, Angie's height went from 58 to 60 inches. What was the percentage increase in Angie's height? (Round to the nearest percentage)

Answers

The percentage increase in Angie's height is 3 %

Solution:

Given that, In one year, Angie's height went from 58 to 60 inches

To find: percentage increase

The percent increase between two values is the difference between a final value and an initial value, expressed as a percentage of the initial value.

The percent increase is given as:

$\text { percent increase }=\frac{\text { final value - initial value}}{\text { initial value }} * 100$

Here in this problem,

Initial value = 58 inches

Final value = 60 inches

Substituting the values we get,

$percent\ Increase = (60-58)/(58) * 100\n\npercent\ Increase = (2)/(58) * 100\n\npercent\ Increase = 0.0344 * 100\n\npercent\ Increase = 3.45 \approx 3$

Thus percentage increase in Angie's height is 3 %
