Answer:
π
V-foam = 4r³( 2 - ----- )
3
Step-by-step explanation:
Let r denote the radius of the sphere. The volume of the sphere is expressed as
V = (4/3)(π)(r³).
Next, understand that the cube's side length is 2r, hence the cube's volume is
V = (2r)³, which equals 8r³.
The volume of the foam is derived from the cube's volume subtracting that of the sphere:
V-foam = 8r³ - (4/3)(π)(r³). This can be simplified to
π
V-foam = 4r³( 2 - ----- )

-10w - 400 = o
w= weeks
o = remaining balance
To find the maximum number of identical packs we see we have 72 pencils and 24 calculators.
This involves discovering the largest number that divides both 72 and 24 evenly,
which is known as the GCM or greatest common multiplier.
To determine the GCM, factor 72 into primes and group them:
72=2 times 2 times 2 times 3 times 3
24=2 times 2 times 2 times 3
Thus, the common grouping is 2 times 2 times 2 times 3, equating to 24.
Therefore, the maximum number of packs is 24.
For pencils:
72 divided by 24=3
Resulting in 3 pencils per pack.
For calculators:
24 divided by 24=1
So, 1 calculator per pack.
The outcome is 3 pencils and 1 calculator in each pack.
Each month she puts in 20......therefore annually she deposits (20 * 12) = 240 y = 240x + 200
Response:
The fence's length is expressed as 6.28x - 150 cm.
Detailed Breakdown:
Assuming the circular pool has a radius (r) of x cm.
As the pool is circular, its circumference represents the length of the fence. Additionally, subtracting the 150 cm for the gate gives us the actual length of the fence.
Length of fence = Circumference of pool – gate's width.
Length of fence = 2 π r – 150
Length of fence = 2 × 3.14 × x – 150
Therefore, the fence length is 6.28x – 150 cm.
