The formula of a circle is A=pi x radius^2
i cant see the blue and red numbers for some reason ill do the other 4 by plugging them in
yellow:153,94 rounded 153,9
green:1385.4
orange3019.1
purple:227
circumference formula c=2 X pi X r
yellow: 43.9
green: 132
orange: 194.8
purple: 53.4
plz correct me if im wrong
Answer:
Area of the shaded region = 23.33 in²
Step-by-step explanation:
Area of a sector = 
Where θ = Central angle subtended by an arc
r = radius of the circle
Area of the sector BCD = 
= 52.36 in²
Area of equilateral triangle BCD = 
= 
=
in²
= 43.30 in²
Area of the shaded portion in ΔBCD = 52.36 - 43.3
= 9.06 in²
Area of sector CAD = 
= 39.27 in²
Area of right triangle CAD = 
= 
=
= 25 in²
Area of the shaded part in the ΔACD = 39.27 - 25
= 14.27 in²
Area of the shaded part of the figure = 9.06 + 14.27
= 23.33 in²
