Answer:
209.55in²
Step-by-step explanation:
Find area of sector CADE
Radius =22 in
Angle=90°
Formula to apply is ;
Ф/360 × π × r² where
Ф=angle of sector, π=3.142 and r =radius of circle

Find area of triangle CAD where base length is 22 inches and height is 22 inches
Area of triangle formula is;
1/2×b×h where b is base and h is height

Find area remaining
380.182-242=138.182in²
Find the area of sector CBDF
Radius=28in
Angle=60°
Formula to apply is ;
Ф/360 × π × r² where
Ф=angle of sector, π=3.142 and r =radius of circle

Area of triangle BDC
The formula to apply is
1/2×a×a×sinФ where a=28 inches and Ф=60°

Remaining area
410.55-339.48=71.075in²
Area created by overlapping circles
138.182+71.075=209.26in²

<h3>Answer:</h3>
We know that,
<u>Area of rectangular bulletin = L × B</u>
- L × 50 = 45
- L = 45/50 = 9/10cm
<u>Hence, Length of rectangular bulletin is 0.9cm</u>.
Answer:
The probability of a student to be in the orchestra or the band is 0.07 or 7%.
Step-by-step explanation:
The probability of a student to be in the orchestra or the band is given by the following formula:
p(orchestra or band) = p(orchestra) + p(band) - p(orchestra and band)
p(orchestra or band) = 0.03 + 0.05 - 0.01
p(orchestra or band) = 0.08 - 0.01
p(orchestra or band) = 0.07
The probability of a student to be in the orchestra or the band is 0.07 or 7%.
