Answer:
BC = 6
AC = square root of 72 or 8.485...
angle A = 45
Step-by-step explanation:
BC = BA
AC^2 = BA^2 + BC^2
angle A = 180-(90+45)
29. B 500min
30. C 3ft
31. im not sure but i think its A 16
Answer:
red segment = 25.12 ft
Step-by-step explanation:
circumference of full circle = (3.14)(24) = 75.36 ft
semi circle = 75.36/2 = 37.68 ft
60° segment = (60/360)(75.36) = 12.56 ft
red segment = 37.68 - 12.56 = 25.12 ft
Answer:
The ferris wheel travelled 434.717 ft.
Step-by-step explanation:
Assuming that the ferris wheel is a perfect circle, then it's height is the same as the diameter of the circle, therefore it's radius is:
radius = height/2 = 246/2 = 123 ft
The distance travelled by the ferris wheel is the same as the length of the arc created by a angle of (9pi/8). The length of an arc is given by:
length = r*(angle in radians)
length = 123*(9pi/8)
length = 434.717 ft
The ferris wheel travelled 434.717 ft.
