Answer: $13
Step-by-step explanation:
C. 523.33
the formula is 4/3*3.14*r^3
R being radius (:
Sin(63)=x/7
0.89100652418= x/7 > <span>0.89100652418 (7) = x/7(7)
</span><span>6.23704566932=x This is the height
</span>the area of a triangle is A=BH/2 or Base * Height /2
A= (<span>6.23704566932)(8)/2
</span>A=<span>24.9481826773 or 24.95 cm^2</span>
A point (-0.8, 0.6) will be a point on the unit circle in the second quadrant. Since it is a unit circle, its radius is 1, and we have
sin(α) = y = 0.6
cos(α) = x = -0.8
tan(α) = y/x = 0.6/-0.8 = -0.75
The angle is α = arccos(-0.8) ≈ 143.13°
______
For the unit circle, the trig values are always the coordinates or their ratio as shown above, regardless of quadrant.
