Answer:
They have the same perimeter but different areas.
Step-by-step explanation:
7x4 is 28, and 9x2 is 18
But 7+7+4+4 is 22 and 9+9+2+2 is also 22
Answer:
$7.25
Step-by-step explanation:
First hour=3.50
still have 1 1/2 hours left =3 half hours
1.25x 3=3.75
3.50+3.75=7.25
Answer:
B = *r^2
(Base of the cone)
Step-by-step explanation:
The volume of the cone is always 1/3 of the volume of a cylinder with the same radius and height.
Volume of the cylinder
V_cylin = ( *r^2 )* h
Where
r is the radius
h is the height
This means the volume of the cone is equal to
V_cone = (1/3)* ( *r^2 )* h
By looking to the equation of the problem
V=(1/3)Bh
We can easily deduce that
B = *r^2
(Base of the cone)
