Answer: There are 8 snake and 3 elephants.
Step-by-step explanation:
Let x= Number of snakes
y= Number of elephants
We know that , snake has no legs elephant has 4 legs.
Then, Total animals = x+y=11 (i)
Total legs = 4y = 12
⇒ y=3 .. (ii)[divide both sides by 4]
Substitute value of y from (ii) in (i) , we get
Hence, there are 8 snake and 3 elephants.
6*16^2=1536 in
A=1536 in
The surface area of the cube is 1536 in.
The unoccupied volume will be the volume of the can minus the volume of the three tennis balls.
V=HπR^2-3(4πr^3)/3
V=HπR^2-4πr^3 where H=height of can, R=radius of can, r=radius of ball
We are told H=7, R=1.5, and r=1.125 (2.25/2=d/2=r) so
V=7π1.5^2-4π1.125^3
V=15.75π-5.6953125π in^3
V≈31.58 in^3
