Answer
This is how too apply it in trig when trying to find a side with only the degree and the side.
Answer:
A circle can intersect a parabola in
1. One point [ when circle just touches the parabola]
2. Two points [ When circle cuts the parabola in two distinct points. ]
3. Three points [Circle just touches at one point and cuts the parabola in two distinct points]
4. Four points [ Either parabola or circle meeting each other or crossing at four distinct points]
Step-by-step explanation:
angle 2 = angle KSL = 63°
angle 5 + angle KSL = 90°
= angle 5 = 90°-63
= 27°
angle 3 = angle 5 = 27°
angle 2+ angle 1 + angle 3 = 180°
=hence angle 1 = 80°
angle 4 = 65°
angle 6 = 90°
angle 8 = 90-63=27°
angle 7 = 65°
question 6 - if the area is 144 then one side is 12ft as the square root of 144 is 12
Area of a circle is πr^2.
The radius of the smaller circle with diameter 10 cm is 5 cm.
The radius of the larger circle with diameter 20 cm.is 10 cm.
Area of larger circle : Area of smaller circle
Area of larger circle = 100π.
Area of smaller circle = 25π.
Ratio = 100π : 25π or 100π/25π.
