Answer:
60cos(25)=54.378467222199
Sector = theta/360° × pi×radius×radius
40/360×22/7×10×10
4/36×22/7×100
1/9×22/7×100
22/63×100
2200/63=34.92 sq feets (approximately)
Option C is the answer . Don't get confused with decimals as maybe the person who provided these options used pi =3.14 instead of what i used i.e. =22/7.
The limit of the function tan 6x/sin 2x as x approaches zero is determined by first substituting x by zero. This is equal to zero over zero which is indeterminate. Using L'hopital's rule, we derive each term in the numerator and denominator separately. This is equal to 6 sec^2 x / 2 cos 2x. when substituted with zero again, the limit is 1/2.
The answer is -2x so two black rectangles
