Answer:
Area of circle is
Step-by-step explanation:
Since angle is given in radians, so using formula for area of sector in radians is given as,
Given area of sector and angle. Therefore substituting the values in above formula,
Cancelling out the common term,
Multiplying with 2 on both sides,
Therefore value of is
Formula for area of circle is,
Substituting the value,
Therefore area of circle is
The answer is 15.9 because 3.9+111=15.9
The <u>second image</u> in the diagram is a hyperbola. As can be seen, the plane cutting the cone can be at any angle but never equal to the slant angle of the cone. This has a very important implication. The plane cuts both cones of the double-napped cone. The third double-napped cone of Figure 3 shows two hyperbolas.
C because coordinates go like: (x,y) so the y is 6 and C is the only answer with the y as a 6
