The radius of the semicircle in the following composite figure is 8.5 millimeters. what is the total area of the composite figure rounded to the nearest hundredth?

Step-by-step explanation:

Radius of semicircle = 8.5 mm

Area of semicircle =

                              =

                              =

Area of triangle =

Area of triangle in figure=

                                       =

So, Area of the figure = Area of semicircle +Area of triangle

                                    =

                                    =

Thus Option B is correct.

Hence the total area of the composite figure rounded to the nearest hundredth is

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
