Similarities:

  • They are both line segments.
  • They are both found in circles.
  • Radius is a half of diameter and diameter is twice the radius making them dependent.
  • Their intersection is always contains the center of the circle.
  • Their set intersection equals to radius and their set union equals to diameter.

Differences:

  • Diameter is longer (unless its 0)
  • Diameter touches two different points on the circumference while radius only one point
  • Center angle of diameter is 180° while of radius is 0° or 360°.
  • The Diameter is constructed via line
  • The Radius is constructed via line or ray

Difference would be that is a diameter is double a radius and a radius is half of a diameter.
A similarity would be that they would are within a circle and touch the center of circle

A rectangular playground is to be fenced off and divided in two by another fence parallel to one side of the playground. Four hu
castortr0y [4]

<em>Answer: h = 120 ft;    w = 80 ft </em>

<em></em>

<em>A = 9600 ft^2</em>

<em />

<em>Step-by-step explanation: Let h and w be the dimensions of the playground. The area is given by:</em>

<em></em>

<em>A = h*w   (eq1)</em>

<em></em>

<em>The total amount of fence used is:</em>

<em></em>

<em>L = 2*h + 2*w + w    (eq2)    (an extra distance w beacuse of the division)</em>

<em></em>

<em>Solving for w:</em>

<em></em>

<em>w = L - 2/3*h = 480 - 2/3*h   (eq3)  Replacing this into the area eq:</em>

<em></em>

<em></em>

<em></em>

<em>We derive this and equal zero to find its maximum:</em>

<em></em>

<em>   Solving for h:</em>

<em></em>

<em>h = 120 ft.  Replacing this into eq3:</em>

<em></em>

<em>w = 80ft</em>

<em></em>

<em>Therefore the maximum area is:</em>

<em></em>

<em>A = 9600 ft^2</em>
