The volume of a sphere is defined as:
V=(4*pi*r^3)/3
then, if we double the radius of the sphere (r=2r):
V=(4*pi*(2r)^3)/3
V=(4*pi*(2^3*r^3))/3
V=(4*pi*r^3)/3*8
Then, the answer is that if you double the radius of the sphere, its volume is increased 8 times.

M < 2 = m < 6...corresponding angles
m < 5 = m < 8....vertical angles are congruent
Omg i have the same question
Answer:
80°
Step-by-step explanation:
∠ABC= ∠ABD+∠CBD
as BD bisects ∠ABC, we have
∠ABC= 2*4x= 8x= 80°
