Answer:
A 50% increase
Step-by-step explanation:
Area = length x breadth
Let illustrate this with an example
original dimensions
length = 4
breadth = 5
area = 4 x 5 = 20
new dimensions
length = 4/2 = 2
breadth = 5 x 3 = 15
area = 15 x 2 = 30
Percentage change = 30 - 20 / 20 x 100 = 50%
A digit in the ten thousands place will always be greater than the one in the thousands place. Even though the number in the ten thousands place is smaller it will still be greater because 10,000>1,000 right? For example,
If you had the number 31,0
Answer:
π
V-foam = 4r³( 2 - ----- )
3
Step-by-step explanation:
Let the radius of the sphere be r. Then the volume of the sphere is
V = (4/3)(π)(r³).
Next, recognize that the side length of the cube is 2r, and that the volume of the cube is thus
V = (2r)³, or 8r³.
Then the volume of the foam is equal to the volume of the cube less the volume of the sphere:
V-foam = 8r³ - (4/3)(π)(r³). This could be factored into
π
V-foam = 4r³( 2 - ----- )
