Answer:

Step-by-step explanation:

1). Since, XM is the radius of the circle,

   Therefore, area of the circle = \pi r^{2}

                                                   = \pi (XM)^2

                                                   = \pi (12)^2

                                                   = 452.39 units²

2). Circumference of a circle = 2πr

                                                = 2π(XM)

                                                = 2π(12)

                                                = 24π

                                                = 75.40 units

3). By applying Pythagoras theorem in ΔYXM,

    YM² = XY² + XM²

    (43)²= (XY)² + (12)²

     1849 - 144 = (XY)²

     XY = 41.29 units

4). tan(∠M) = \frac{\text{Opposite side}}{\text{Adjacent side}}

                  = \frac{XY}{XM}

    m∠M = tan^{-1}(\frac{41.29}{12} )

              = 73.79°

5). Area of ΔXYM = \frac{1}{2}(\text{Base)}(\text{Height})

                             = \frac{1}{2}(41.29)(12)

                             = 247.74 square units

6). Area of the minor sector created by ΔXYM = \frac{\theta}{360}(\pi r^2)

                                                                             = \frac{73.79}{360}(452.39)

                                                                             = 92.73 units²

Rzqust [24]

Answer:

1p = r

Step-by-step explanation:

You are asking how many 1-foot pieces you can make out of a 5 foot piece of ribbon. You are asking for an equation.

p = the # of pieces

r = the amount of ribbon

So lets try the equation:

1p   = r

1(4) = r

1*4 = 4

4    = r
