Answer:
B: 13000 m²
Step-by-step explanation:
To find how much wood is used, we will have to find the surface area of the wooden building.
Formula for surface area of a rectangular pyramid is;
SA = lw + l√(h² + w²/4) + w√(h² + l²/4)
We are given;
l = 100 m
w = 50 m
h = 40 m
Thus;
SA = (100 × 50) + 100√(40² + 50²/4) + 50√(40² + 100²/4)
SA = 5000 + 4717 + 3201.56
SA = 12918.56
Approximating to 2 significant figures gives;
SA = 13000 m²

<u>QUESTION 1</u>
The given data set for the expenditure is
The formula for calculating the mean is given by,
We need to add all the expenditure and divide by the total number of days.
This gives us,
to the nearest hundredth.
<u>QUESTION 2</u>
The standard deviation of the data set is given by the formula;
This implies that,
This will give us,
to the nearest hundredth,
.
<u>QUESTION 3</u>
The variance is the square of the standard deviation.
To the nearest hundred gives,
The area of the circle is found by multiplying the value of PI by the radius raised to the power of 2
the circumference of a circle can be found in 2 ways. If you know the diameter of the circle multiply that by the value of PI. If the radius of the circle is known multiply that by 2 then multiply that by the value of PI.
The information needed is what value of PI to use and either the radius or diameter of the circle.
The circumference is the distance around the circle , so you would want to know the circumference to determine the number of rotations a tire makes.
