Radian measure is given by dividing the length of an arc by the radius of a given circle. Such that an arc that subtends an angle of 1 radian to the center of a circle is equivalent to the radius of the circle.
Therefore; θ = s/r where θ is the angle subtended in radians, s is the length of the arc and r is the radius of the circle.
Hence; r = s/θ
= 12π ÷ (4π/7)
= 12 × (7/4)
= 21 inches
Answer:
C. From each intersection point, draw an arc above side EF so that the two arcs cross.
Step-by-step explanation:
I just took this and got it right
Its not a triangle at all in order for it to be a triangle the side length of 4 and the side length of 6 needs to be more than 12 so that the lines can connect.
The nearest tenth means to the first digit of the decimal. Because there's a 5 after the 1, we round up, so your answer is 0.2.
