Answer:
Mr. Drew needs 167.3 ft of wood
Step-by-step explanation:
we know that
The area of a square is
where
b is the length side of the square
we have
substitute in the formula and solve for b
square root both sides
To determine the total length of wood , calculate the perimeter of the sandbox
The perimeter of the sandbox is equal to the perimeter of 5 squares
so
substitute the value of b
therefore
Mr. Drew needs 167.3 ft of wood
Answer: CSA = 22.9m^2
Step-by-step explanation:
The cross sectional area of the cylinder perpendicular to the length, is the area of the circular base or top of the cylinder. It can be derived mathematically using the area of a circle.
Cross sectional area = πr^2
Where r is the radius of the cylinder
r = 2.70m
CSA = π×2.70^2
CSA = 22.9m^2
Answer:
Step-by-step explanation:
Keep in mind that the tangent function is negative in Quadrants II and IV.
Of the three possible answers, the 2nd is invalid because the tangent is positive in Q III.
If the reference angle were in Quadrant II and had the value 30° (second possible answer), then the opposite side would be +1, the adjacent side -√3 and the hypotenuse 2. Based on this, the tangent of theta would be opp / adj, or +1 / (-√3) or -√3/3. This is correct.
