The volume of a sphere is calculated like so:
v = 4*pi*r^3/3
so half sphere will have half that volume:
v = (<span>4*pi*r^3/3)(1/2)
</span>v = <span>4*pi*r^3/6
</span>plug in the data:
v = <span>4*pi*(10)^3/6
</span>v = 2094.4
that is the volume of the half sphere
Answer:
no solution !
Step-by-step explanation:
because when you do the solving steps:
Distributative Property
combine like terms
x goes away bc you subtract 3x from 3x
therefor NO solution
Hope this helps ;)
The area of the garden is the amount of space on the garden.
- The area of the total garden is (x + 15)(x + 20)
- The width of the pathway is 1 meter
<h3>The expression of the area</h3>
The dimensions of the garden is given as:
15 meters by 20 meters
Let the width of the pedestrian pathway be x.
So, the area of the total garden is:
<h3>The width of the pathway</h3>
In (a), we have:
The total area is given as: 336.
So, we have:
Expand
Collect like terms
Evaluate
Expand
Factorize
Factor out x + 36
Solve for x
x = -36 or x =1
The width cannot be negative.
Hence, the width of the pathway is 1 meter

Answer:
The answer is 48p^3 - 24p^2 + 24p - 48
Answer:
x = 67 degrees
Step-by-step explanation:
180 = 46 + x + x
180 = 46 + 2x
180 - 46 = (46 - 46) + 2x
134 = 2x
134/2 = 2x/2
x = 67
