- First find the area of the whole circle
The equation is :
πr^2
Substitute the radius in:
π(5)^2
Solve:
Area of full circle = 25π
(Note : leave this answer in terms of 'pi' so it is easier to handle
Next, find the area of the sector
The equation for this is:
(angle/360) x πr^2
Substitute the values in:
(80/360) x π(5)^2
Solve :
Area of sector = (50/9)π
Now, find the area of the triangle:
1/2 absinC
Substitute the values in:
1/2(5)(5) x sin(80) = 12.31009691
Subtract this answer from the area of the sector
Answer = 5.14319607
Subtract this from the area of the whole circle
Answer = 73.39662073
To the nearest tenth, that would be 73.4 cm^2

Answer:
Hey there!
(2p - 3)(4p2 + 6p + 9) is equal to 8p^3+27. This is just a sum of cubes!

Answer:
cos^-1 (12/13) or 22.6°
Step-by-step explanation:
sohcahtoa you have the adjacent side which goes over hypotenuse and since you are solving for angle it will be inverse of cos
Conversion factors:
2 pints = 1 quart
4 quarts = 1 gallon
60 minutes = 1 hour
15 pints/minute x 60 minutes/hour x 1 quart/2 pints x 1 gallon/4 quarts = 112.5 gallons/hour
