A is center of one circle and C is the center of the other circle. Select all line segments that must have the same length as se
Dominik [7]

Based on the circles shown in the diagram attached above, the line segments that must have the same length as segment AB are:

  1. Segment BC.
  2. Segment CD.

<h3>What is a circle?</h3>

A circle can be defined as a closed, two-dimensional curved geometric shape with no edges or corners. Also, a circle refers to the set of all points in a plane that are located at a fixed distance (radius) from a fixed point (central axis).

<h3>The equation of a circle.</h3>

Mathematically, the standard form of the equation of a circle is given by;

(x - h)² + (y - k)² = r²

Where:

  • h and k represents the coordinates at the center.
  • r represents the radius of a circle.

<h3>What is a line segment?</h3>

A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

Based on the circles shown in the diagram attached above, the line segments that must have the same length as segment AB are:

  1. Segment BC.
  2. Segment CD.

A rectangular swimming pool is 25 ft long and 20 1/2 ft wide, and it must be filled to a depth of 4 1/2 ft. One cubic foot of wa
bazaltina [42]

ANSWER

307½ gallons of water

EXPLANATION

The volume of the rectangular swimming pool is

V = l \times w \times h

where l=25ft and w=20½ ft.

when it is filled to a depth of 4½ ft ,then the height is , h=4½ ft.

We substitute these values into the formula to get:

V = 25\times 20.5\times 4.5

V = 2306.25 {ft}^{3}

If one cubic foot of water is 7½ gallons, then 2306.25 cubic feet will be

\frac{2306.25}{7.5}  = 307.5gallons

We need 307.5 gallons of water to fill the pool.
