Answer:
8 times larger
Step-by-step explanation:
The radius of the large sphere is double the radius of the small sphere.
Note the equal sign. What you do to one side, you do to the other. Isolate the a.
Add 4 to both sides
a- 4 (+4) = 15 (+4)
a = 15 + 4
a = 19
19 is your answer for a

Answer:
Step-by-step explanation:
apply the inverse properties of logarithmic and exponential functions to simplify
Inverse property of log says that
we apply this property in our problem. ln has same base 'e' . so ln and e gets cancelled
