The area of the cross section of the column is
Explanation:
Given that a building engineer analyzes a concrete column with a circular cross section.
Also, given that the circumference of the column is meters.
We need to determine the area of the cross section of the column.
The area of the cross section of the column can be determined using the formula,
First, we shall determine the value of the radius r.
Since, given that circumference is meters.
We have,
Thus, the radius is
Now, substituting the value in the formula
, we get,
Thus, the area of the cross section of the column is
We have been given that a company makes wax candles in the shape of a solid sphere. Each candle has a diameter of 15 cm. We are asked to find the number of candles that company can make from 70,650 cubic cm of wax.
To solve our given problem, we will divide total volume of wax by volume of one candle.
Volume of each candle will be equal to volume of sphere.
, where r represents radius of sphere.
We know that radius is half the diameter, so radius of each candle will be cm.
Now we will divide 70,650 cubic cm of wax by volume of one candle.
Therefore, 40 candles can be made from 70,650 cubic cm of wax.
