Answer:
The area of the figure is 63.25 square feet
Step-by-step explanation:
we know that
The area of the figure is equal to the area of semicircle plus the area of triangle
step 1
Find the area of semicircle
The area of semicircle is
we have
----> the radius is half the diameter
substitute
step 2
Find the area of the triangle
The area of triangle is equal to
we have
substitute
step 3
The area of the figure is equal to
substitute
Answer:
1. D -4
2. B -16
3. B. 37
4. E 13
5. C -646
6. E 12
Step-by-step explanation:
The area of a circular sector of central angle α (in radians) in a circle of radius r is given by
... A = (1/2)r²×(α - sin(α))
Your area is expected to be computed as the sum of the areas of a sector with angle π/3 in a circle of radius 8 and a sector with angle π/2 in a circle of radius 6.
... A = (1/2)8²×(π/3 - sin(π/3)) + (1/2)6²×(π/2 - sin(π/2))
... A ≈ 16.07
Radii are in inches so the units of area will be in². The appropriate choice is
... 16.10 in²
_____
It should be noted that the geometry described is impossible. Chord CD of circle A will have length 6√2 ≈ 8.4853 inches. Chord CD of circle B will have length 8 inches. They cannot both be the same chord.
Answer:
1.) 256 miles
2.) 2 1/2 ( 2.5 ) pages a day
Step-by-step explanation:
1.) ( 256 * 2.4 = 640 )
2.) 250 / 20 = 2.5
The answer is about 13.9927.
You would divide 52/11 and then subtract that decimal by 18.65.
18.65-4.7272=13.9927.
