Answer:
113.04 cm³
Step-by-step explanation:
diameter = 6cm
so radius = 3cm
Volume of sphere = 

= 4 * 3.14 * 3 * 3 *3 / 3
= 4 * 28.26
= 113.04 cm³

Answer:

Step-by-step explanation:
-A hemisphere is equivalent to half of a sphere.
- The area of a sphere is given by the formula:

-Given that r=3.6m, the hemisphere's volume can be calculated as:

Hence, the hemisphere's volume is approximately 
First we can change the miles per hours into feet per hour. Every mile is 5280 feet so multiply 58 by 5280. 58*5280=306,240. Now you have 306,240 feet per hour which you then divide by 60 twice to get per second. 306,240/60=5,104ft per minute now divide again to find per second. 5,104/60≈85.1feet per second.
