Got it correct
From right triangle trigonometry, we have the following:

,
where the "opposite side" means the opposite side to angle with measure

, and "adjacent side" means the adjacent side to angle with measure

.

is a constant which can be found using a calculator.
In the calculator of the pc press: view - scientific - 35 - tan.
This gives

Thus, back in the equation

we substitute as follows and solve:


Answer: 8.4 cm
Answer: Four-thirdsπ(6)³
Step-by-step explanation: The formula for the volume of a sphere is attached in the image down below.
Notice that two of the options listed have <em>three-fourths</em> but we use <em>four-thirds </em>to find the volume of a sphere. This means that we can eliminate the 1st and the 3rd option.
Now, we will multiply that by π and then by the radius cubed which is also written as 6³. This means that our answer would be the second option.

If you multiply the two numbers, you will have 36 + 78i.
*I assumed you had a typo in the first expression, it is generally written as 6 + 3i. If you meant, 6i + 3i, it should have been just 9i.
To find this product, we use the foil method.
(6 + 3i)(10 + 8i)
60 + 48i + 30i + 24i^2
60 + 78i + 24(-1)
34 + 78i
