Formula: V = (2/3) π r 3.
Radius is 3cm.
So, now we can plug it in to solve for the volume.
V = (2/3) π 3^3
First, let's multiply 3^3.
3^3 = 27
Then, 27 x π = 84.82
After, multiply by 2/3.
84.82 x 2/3 = 56.55
Lastly, round 56.55 to the nearest tenth of a cubic centimeter.
56.55 = 56.6
Therefore the volume of a hemisphere with a radius of 3cm is 56.6cm^3.

Solution
For this case we can do the following:
A) 15, 21
LCM= 105
15= 3*5
21 = 7*3
LCM= 3*5*7
b) 15,30
LCM= 30
15= 3*5
30 = 2*5
LCM= 2*3*5= 30
c) 24,72
LCM= 72
24= 2*3*4
72= 2* 2*2*3*3
LCM= 2*2*2*3*3
d) 16,42
LCM= 336
16= 2*2*4
42= 2*3*7
LCM= 2*2*3*7*4
e) 8,30
LCM=120
8= 2*4
30= 2*3*5
LCM= 2*3*4*5=120
f) 18,30
LCM=90
18= 2*3*3
90= 2*5*3*3
LCM= 2*5*3*3
g) 8,16,20
LCM= 80
8= 2*2*2
16= 2*2*2*2
20= 2*2*5
LCM= 2*2*2*2*5
