The radius of each of the smaller circles is 1 in.  Find the area of the shaded region to the nearest unit.  I have no idea where to begin.  I am trying to teach myself a middle aged woman simple math.  I figured it's never too late to learn.  Thanks  </p>Davene FajackDavene Fajack48questionTue, 20 Oct 2009 03:08:32 GMThttp://yedda.com/questions/science_mathematics_273993889712605/?src=rss:qb:qbihttp://yedda.com/questions/science_mathematics_273993889712605/C_piD_D_19_098593_1_value_pi_3_1416_862717055173575?src=rss:qb:qbi<p>C = piD</p> <p>D = 19.098593</p> <p>D = 19.1"</p> <p>The value of pi is about 3.1416</p> <p>The remainder of your questions require visual data.</p> <p>Jay</p>Jay aka EETJay aka EET54answer3.0Tue, 20 Oct 2009 03:47:25 GMThttp://yedda.com/questions/science_mathematics_273993889712605/C_piD_D_19_098593_1_value_pi_3_1416_862717055173575?src=rss:qb:qbihttp://yedda.com/questions/science_mathematics_273993889712605/Regarding_Circle_Circles_fun_273533797518459?src=rss:qb:qbi<p>Regarding the Circle & Circles are fun!</p> <p>Circumference is equal to Pi times the Diameter:</p> <p>The Radius is equal to Diameter divided by 2:</p> <p>Area is equal to Pi times the radius squared:</p> <p>Pi is equal to 3.1415926!</p> <p>Your Welcome!</p>Dr. BennettDr. Bennett68answer3.0Fri, 23 Oct 2009 15:20:57 GMThttp://yedda.com/questions/science_mathematics_273993889712605/Regarding_Circle_Circles_fun_273533797518459?src=rss:qb:qbihttp://yedda.com/questions/science_mathematics_273993889712605/60_pi_19_0968_1_inches_nearest_inch_735568117538406?src=rss:qb:qbi<p>60/pi ~ 19. 0968... ~ 19.1 inches to nearest inch</p> <p>"Shaded" means they overlap <span style="text-decoration:underline;">somehow</span>, but we cannot see your diagram, or</p> <p>get the idea from your words, of <span style="text-decoration:underline;">how</span> the smaller ones are placed on the larger.</p> <p>Please give more details.</p> <p>If they are apart from eachother with their centres on the circumference of the larger, a very rough estimate would be pi X 8^2 minus 2 X (1/2) pi ~ 63 pi ~ 198 square units.</p> <p>Regards - Ian</p>IanIanmale61answer4.0Sun, 25 Oct 2009 23:00:50 GMThttp://yedda.com/questions/science_mathematics_273993889712605/60_pi_19_0968_1_inches_nearest_inch_735568117538406?src=rss:qb:qbi
