Volume of sphere = 4/3 x pi x r^3

Volume of large sphere:

4/3 x 3.14 x 14^3 = 11488.21 cubic cm

Volume of smaller sphere:

4/3 x 3.14 x 2^3 = 33.49 cubic cm

Number of small spheres = volume of large sphere/ volume of small sphere

11488.21 / 33.49 = 343.03

Round to 343 small spheres

84% of what is 147?
levacccp [35]

Answer:

175.

Step-by-step explanation:

In this question, translate the words into the symbols. "84" is 84, "%" is 1/100, "what" is x, the unknown, "of" is *, "is" is =, and "175" is 175. Therefore the words can be translated into an equation given below:

84 * x / 100 = 147

84x = 14700

x = 175.

Therefore, 84% of 175 is 147!!!
