Answer:Area of the shaded region is 73.6 cm^2
Step-by-step explanation:
The circle is divided into two sectors. The Smaller sector contains the triangle. The angle that the smaller sector subtends at the center of the circle is 80 degrees. Since the total angle at the center of the circle is 360 degrees, it means that the angle that the larger sector subtends at the center would be 360 - 80 = 280 degrees
Area of a sector is expressed as
Area of sector = #/360 × πr^2
# = 280
r = 5 cm
Area of sector = 280/360 × 3.14 × 5^2
Area of sector = 61.06 cm^2
Area of the triangle is expressed as
1/2bh = 1/2 × 5 × 5 = 12.5
Area of the shaded region = 61.06 +
12.5 = 73.6
(12.65) is your total answer because 20/100 x63.25 gives you 12.65
Brandon is 24 michael is 72...hope that helps :D
Bobby. If you find the common denominator here which is 12 then Mina has 4/12 red pencils, bobby has 8/12 red pencils, and julia has 6/12 repent ils. Therefore bobby has the most red pencils.
