Answer:
Step-by-step explanation:
.
Recall that .
So, we want .
This simplifies to .
We know that .
So, our expression is , which can't be simplified more.
So, our answer is and we're done!
Multiply by 9 then divide by 5.
The volume of the spherical ball will be 4 · π · 3² · 10⁶ cubic cm. Then the correct option is A.
The complete question is attached below.
<h3>What is the volume of the sphere?</h3>
Let r be the radius of the sphere.
Then the volume of the sphere will be
V = 4/3 πr³ cubic units
The radius of the sphere is 3·10² cm.
Then the volume of the spherical ball will be
V = 4/3 πr³
V = 4/3 π(3 x 10²)³
V = 4/3 · π · 3³ · 10⁶
V = 4 · π · 3² · 10⁶ cubic cm
Then the correct option is A.
