Answer:
1539.38
Step-by-step explanation:
this can be figured out as an entire cylinder and then take 1/2 of that
area of a circle of 7 cm
area = 
area = 153.938
volume = 153.938 * 20
volume = 3078.7608
and take 1/2 of that to find volume of the half cylinder
3078.7608 / 2 = 1539.38
Multiply all of them together.10*9*8 and so on...

Answer:
729 m³
Step-by-step explanation:
Volume of a cube (or a rectangular prism) formula:
lwh
l is length
w is width
h is height
Here, the length, width, and height measures 9 m.
So
9 × 9 × 9 or 9³ = 729
Answer:
P(red) = .3
P(yellow) = .3
75 cubes in the box
Step-by-step explanation:
The probability has to add to 1
Since the number of red cubes equals the number of yellow cubes the probability has to be the same
.4 + x+x = 1
.4 +2x = 1
2x = 1-.4
2x = .6
Divide by 2
x = .6/2
x = .3
P(red) = .3
P(yellow) = .3
We know that
P(blue) = .4 = number of blue cubes/ total number of cubes
.4 = 30/total
total = 30/.4
total = 75
