Answer:
The correct answer is option A
Step-by-step explanation:
The volume of a cylinder is given by
Substituting the values of radius and height in above equation, we get -
1/5 = 0.2 = 20%
100% - 20% - 10% = 70%
He left 70%
<33
Answer: 320 toys
Step-by-step explanation:
We can use an expression to solve this question.
8 (25 + 15)
8 (40)
320
Answer is - 10
Step-by-step explanation:
Let the missing number be ‘x’
-8-x = 2
-x = 2 + 8
-x =10
x = -10
Answer:
32 cubic feet
Step-by-step explanation:
To know the volume of a figure we have to calculate the area of its "base" and then multiply it by its height.
In this case we have a rectangular hole that has an area of 8 square feet.
As we said before:
Volume = Area x height.
If we substitute the value of the area of the rectangle and the height (or depth in this case) we would get:
Volume = 8 x 4 = 32 cubic feet.
Thus, the volume of John's hole is 32 cubic feet.
