Answer:
648 cubic centimeters
Step-by-step explanation:
6×9×12=648
volume of the center sphere = 4/3*PI*r^3
r = 3 ( given in the picture)
so 4/3 * 3.14 *3^3 = 113.04 cubic feet
volume of 1 cone: pi *r^2 *h/3
r = 3 and h=3 ( given in the picture)
so 3.14 * 3^2 * 3/3 = 28.26 cubic feet
there are 4 cones so 28.26* 4 = 113.04 cubic feet
113.04 + 113.04 = 226.08 cubic feet
rounded to nearest cubic foot = 226 cubic feet
Answer:
D/About 18.85
Step-by-step explanation:
So, Using the Circle Circumfrince Formula:

There you go!
Hope this helps!
P.S. Stay Safe!
291-186=105 (total earned through wages)
105/5=21
Therefore she worked 21 hours
The ratio would be 14:6
If you reduce it it would be 7:3
