Answer:
40°
Step-by-step explanation:
90°-50°=40°
area = PI x r^2
radius = 1/2 diameter
1/2 of 8 = 4
3.14 x 4^2 = 3.14 x 16 = 50.24 square inches ( answer may vary depending on what you use for PI. 3.14 is common)
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
