Answer:
|-2| + |5|
Step-by-step explanation:
Dennis walks from (–5, –2) to (–5, 5) on the map.
Point on the format (x,y). On the x-coordinate, he stayed at the same position, x = -5, so it does not enter the distance calculation.
On the y-coordinate, he went from -2 to 5, so the distance is of:
So the correct option is |-2| + |5|
Answer:
Length of arc AD = 15.7 cm
Step-by-step explanation:
Length of arc =
Here, θ = Central angle subtended by the arc
r = radius of the circle
From the picture attached,
Central angle subtended by arc AD = 360° - (180° + 66.4°)
= 113.6°
Length of arc AD =
=
= 15.655 cm
≈ 15.7 cm
Length of arc AD = 15.7 cm
