In two circles, but the radius of the
kipiarov [429]

Answer:

6.76 m^2

Step-by-step explanation:

Large circle area = pi r^2 = pi L^2  = 60.84

              then L = sqrt (60.84/pi)

Small circle radius = r =  1/3 L

   small circle area = pi r^2

                                 = pi ( 1/3 sqrt (60.84/pi))^2  =  6.76 m^2

Answer:

x = 82°

y = 59°

z = 39°

Step-by-step explanation:

∠x = 1/2(134° + 30°) = 82°

∠z = 180° - 59° - 82° = 39°

arc DF = 2(39°) = 78°

arc DB + arc DF = 134° + 78° = 212°

draw a diameter down from point B to the opposite side of the circle, call that point P:

arc BDP = 180°

(arc BDF) 212° - 180° = 32° (arc PF)

∠PBG = 1/2(32°) = 16°

∠DEB = 1/2(134°) = 67°

∠DBE = 180° - 59° - 67° = 54°

(∠DBE) 54° - (∠z) 39° + (∠PBG) 16° = (∠PBE) 31°

y = 90°- 31° = 59°
