Answer: A) 0.18 cm²
Step-by-step explanation:
To calculate the area of a parallelogram you must apply the formula shown below:
Where b is the base and h is the height of the parallelogram.
You know the values of the base and the value of the height.
Therefore, when you susbstitute these values into the equation shown above, you obtain the following result:
You use FOIL (first, outer, inner, last) to check your answer. Eg: (x-4)(x+3)then distribute by using FOIL to get 2 2
x +3x -4x -12 then simplify to get x -x -12
Because 3/5 and 5/3 make a product of 1, so you have one x on the right side.
Using conversion of units and volume of a cylinder, it is found that 23.17 cubic yards of concrete are needed, option D.
The volume of a cylinder of radius r and height h is given by:
In this problem:
- We want the volume in cubic yards, thus, the units of radius and height have to be in yards.
- 32 inches in diameter, thus 16 inches of radius. Since each inch has 0.0278 yards, this is a radius of 0.44 yards, thus
. - Height of 8 feet, and since each feet has 0.33 yards, this is a height of 2.67 yards, thus
- 14 poles, thus the volume is multiplied by 14.
Then:
23.17 cubic yards of concrete are needed, option D.
