Answer:
r = 0.9 in.
Step-by-step explanation:
the volume equation of a cone is πr^2h/3 in this case you have the volume and the height measurements but youre missing the radius, so you have to divide the volume by the rest of the equation and backtrack and when you do, you get a radius value of 0.9

Let's say
is the measure of the first angle and
is measure of the supplement of
. We know that supplementary angles add up to 180°, so
. We also know that
. Therefore,
. It follows that
, therefore, the first angle is 174° and the second angle is 6°.

Answer:
In order to determine the number of wax cubes needed to make the candle, we divide the volume of the pyramid by the volume of the cube. That is,
number of wax = volume of mold / volume of wax
The formulas are,
number of wax = (1/3)Ah / s³
Where A is the area of the base, in this case 9 cm x 9 cm which is equal to 81 cm². Substituting the known values from the given above,
number of wax = (1/3)(81 cm²)(10 cm) / (4 cm)³ = 4.21
Thus, approximate number of wax should be 4.21. If we are to round this off to the nearest whole number, we will get 5 (considering that we want rather to have excess than missing items)
