Answer:
5A) radius = 9 ft
5B) diameter = 18 ft
5C) fencing length = 56.52 ft
5D) 6.35 days
Step-by-step explanation:
Radius is given when it is 9 ft of rope (outside to center of circle)
Diameter is two times radius = 18.
Circumference(fence length) = 2 * 3.14 * 9 = 56.52.
Area circle = 3.14*(9*9) = 254.34. 254.34/40 = 6.35

A 86.5 b 52 C-2.9 d. -11.6
Answer:
a = 3 , b = 5
Step-by-step explanation:
It’s an isosceles triangle because angle A is equal to angle C (63deg). This is calculated by 180 - 117 = 63 degrees.
Using the exterior angle is equal to the interior angles property, angle A is equal to 117 - 54 (which is 63).
Because these two angles are equal to eachother, the triangle is isosceles.
