Find the area of the shaded region. round the the nearest tenth.

226.084 sq.m.

Step-by-step explanation:

Radius of circle = 18.6 cm

Area of sector =

Area of sector =

Area of sector =

Area of triangle =

a = OA = radius = 18.6 cm

b = OB = radius = 18.6 cm

x =123 °

Substitute the values in the formula

Area of triangle =

Area of triangle =

So, Area of shaded region = Area of sector - Area of triangle

                                            =

                                            =

Hence the area of the shaded region is 226.084 sq.m.

Step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
