Answer:
r>0 and V(r)>0
Step-by-step explanation:
Number one: There arent no negative volumes
Number two: There aren't Negative radi
Thus V(r) and r must be more noteworthy than one.
I connect the chart V(r)=5 Pi r^2
The space would be (0,infinity)
The run would be (0, infinity)
Answer:
X = -6 - 3y
Y = -1
Step-by-step explanation: Solve for X first using basic algebra. Plug in X vaalue to original equation and solve. -6 - 3y + 3y = -6. Solve by adding 6 to both sides of the equation and dividing -3y by 3y.
Answer:
5.023 I believe
Step-by-step explanation:
Answer:
The larges perimeter she can make becomes is 96 ft
Step-by-step explanation:
Here we note that the available brick is 47 ft²
Therefore, she has 47 square cement blocks
Let the length of the sides of the rectangle with the most perimeter be x and y
Then 2·x + 2·y = 47 which is not possible because 47 is a prime number
Hence we have the possible sides of the rectangle is a single line of square blocks such that
x × y = 47 ft² where y = 1 hence x = 47
The larges perimeter she can make becomes, 2 × (1 + 47) = 96 ft.
Answer:
3.04 m²
Step-by-step explanation:
Surface Area =0.8x0.4 = 0.32 (two of these - one on each end)
1x0.4=0.4 (two of these - top and bottom) (Strange to cover bottom with screen, but have to follow the directions.)
1x0.8=0.8 (two of these - front and back)
TOTAL = 0.32+0.32+0.4+0.4+0.8+0.8=3.04
