Answer:
85°
Step-by-step explanation:
m∠4 measures 85 degrees.
m∠4 and m∠5 are alternate interior angles.
The alternate interior angles theorem states that <u>all pairs of alternate interior angles are congruen</u>t, or equal.
m∠4 ≅ m∠5
So, m∠5 should also be 85° as well as m∠4.
Answer:
3 cm
Step-by-step explanation:
First, find the volume of the cone.
V = 
r²h
V =
(3.14)(9)(12)
V = 113.04
This means the sphere is also 113.04
Use the formula V = 
r³
113.04 =
(3.14)r³
113.04 = 4.19r³
26.98 = r³
3 ≈ r
