Find the area of the crescent-shaped region (called a lune) bounded by arcs of circles with radii r = 2 and r = 14
1 answer:
the complete question in the attached figure
Let
A1-------> half of the area of the blue circle
A2-------> area of the circular segment formed by the diameter of the blue circle treated as a chord of the red circle
A3---------- > area of the crescent-shaped region
A3=A1-A2A1=pi*2²/2=6.28
Area of the circular sector
if 360 º corresponds to an area of pi*14²
2*arc sin(2/14)------------------- X
X=16.43*pi*14²/360---------- > X=28.10
Triangle area:
------- >(4/2)*√(14²-2²=27.72
Area of the circular segment A2=Area of the circular sector-Triangle area
A2=28.10-27.72=0.38
A3= A1-A2=6.28-0.38=5.90 units²
the answer is 5.90 units²

Answer:
374.1
Step-by-step explanation:
Area of Hexagon =
The ' a ' is the side length.
So now we just plug in the values
= 374.12
Explanation:
At each step, the product of the quotient digit and the divisor is subtracted from the dividend. This gives you the new dividend.
When the quotient digit is 7, the product of 7 and 5 is subtracted from the dividend. The dividend at that point is 35, so you have 35 - 35 = 0. The 0 is the next dividend. Among other things, that tells you you're done. (Any additional quotient digits will be zero.)
