what is the volume of a sphere with a radius of 18 units?

a. 77767 units3
b. 12967 units3
c. 58327 units
d. 19447 units3

Step-by-step explanation:

Volume of a sphere= 4/3πr³, where π = 3.142. Substitute for the π and r in the equation, we now have,

4/3 x 3.142 x 18 x 18 x 18 = 24432units³

So going by the formulae for finding the volume of a sphere, the options may not contained the answer.

(D)  Step 1:

     Step 2:

Step-by-step explanation:

The given equation is:

Now, Step 1. Simplifying the above equation, we get

Step 2. Further simplifying the equation by adding 42 on both sides, we get

=

Thus, from all the option, Option D is correct as it is equivalent to the above steps.
