The cost of 1kg of coal mined from the ore is $0.0397
Data;
<h3>The Cost of 1kg of Coal</h3>
To find the cost of 1kg of coal, we can simply and equate 1 ton to its equivalent in ton and the solve.
![1ton = 907kg\\](https://tex.z-dn.net/?f=1ton%20%3D%20907kg%5C%5C)
let's write this and equate it
1 ton = $35.99
907kg = $35.99
1kg = x
Let's cross multiply both sides and solve for x
![907kg = \$35.99\\1kg = x\\x = \frac{1 * 35.99}{907} \\x = \$0.0397](https://tex.z-dn.net/?f=907kg%20%3D%20%5C%2435.99%5C%5C1kg%20%3D%20x%5C%5Cx%20%3D%20%5Cfrac%7B1%20%2A%2035.99%7D%7B907%7D%20%5C%5Cx%20%3D%20%5C%240.0397)

Answer:
1779.33 mm³
Step-by-step explanation:
We are given a candle in a form of a cylinder and a cone
Dimensions;
Common radius is 5 mm
Height of the cylinder is 20 mm
Height of the cone is 8 mm
We are required to determine the amount that it can hold.
To answer the question we are going to determine its volume
Cylinder;
Volume of a cylinder is given by;
V = πr²H
Taking π to be 3.14
Then ;
Volume of cylinder = 3.14 × 5mm² × 20 mm
= 1570 mm³
Cone
Volume of a cone is given by;
V = 1/3πr²H
That is;
Volume =1/3 × 3.14 × 5mm² × 8 mm
= 209.33 mm³
Therefore;
Volume of the solid = 1570 mm³ + 209.33 mm³
= 1779.33 mm³
Thus, the volume of the solid is 1779.33 mm³
