Answer:
Volume of sphere = 4.186 cubic inches
Step-by-step explanation:
Radius of sphere = r = 1 inch
Volume of sphere = ?
The formula used is: 
Putting value of radius and π and finding volume:

So, Volume of sphere = 4.186 cubic inches

Answer:</h2>
Option: D is the correct answer.
D. 0.45
<h2>
Step-by-step explanation:</h2>
The results of the experiment are given as follows:
Coin Experiment Side of Coin Number of Tosses
Heads 18
Tails 22
This means that total 40 experiments were performed.
( Since 18+22=40)
Also, the number of times head turn up=18
Hence, the experimental probability of getting heads is:
Ratio of number of times head turn up to the total number of experiments performed.
Hence,

Hence, the experimental probability of getting head is:
0.45
