Answer:
4th one
Step-by-step explanation:
For this case we have that by definition the volume of a cylinder is:
V = ((pi) * (r ^ 2)) * (h).
Where
r: radio
h: height.
Also we have
r: d / 2
Where,
d: diameter.
Substituting we have:
V = ((pi) * ((d / 2) ^ 2)) * (h).
V = (pi) * (((6) / 2) ^ 2) * (5).
V = 45pi m ^ 3
Answer:
The volume of a circular cylinder is:
V = 45pi m ^ 3
Volume of a cone = (1/3) pi x r^2 x h
Volume of a cylinder = pi x r^2 x h
Volume of the cylinder = pi x 2^2 x 3 = 37.68 cubic inches
Now set the volume for the cone to the volume of the cylinder and solve for the height.
37.68 = (1/3) x pi x r^2 x h
37.68 = (1/3) x pi x 3^2 x h
37.68 = (1/3) x pi x 9 x h
37.68 = 9.42 x h
h = 37.68 / 9.42
h = 4
The height of the cone is 4 cm.
Answer:
$2.34
Step-by-step explanation:
7.76+4.50+1.90+1.90+1.60=17.66
20-17.66=2.34
No because a square pyramid must hav a square for its base and a square is not a triangle
