Find the value of x. Round the length to the nearest tenth.
Mamont248 [21]
From right triangle trigonometry, we have the following:

\displaystyle{ tan(35^o)= \frac{opposite \ side }{adjacent \ side }, 


where the "opposite side" means the opposite side to angle with measure 35^o, and "adjacent side" means the adjacent side to angle with measure 35^o.

tan(35^o) is a constant which can be found using a calculator.

In the calculator of the pc press: view - scientific - 35 - tan.

 This gives tan(35^o)=0.7


Thus, back in the equation \displaystyle{ tan(35^o)= \frac{opposite \ side }{adjacent \ side } we substitute as follows and solve:


\displaystyle{0.7= \frac{x }{12 }\\\\

x=0.7\cdot12=8.4

What is the volume of a right circular cylinder with a radius of 4 m and a height of 4 m?
CaHeK987 [17]

Answer:

64π m³

Step-by-step explanation:

The general formula for the volume of a cylinder:

V = πr²h, where 'r' is the radius and 'h' is the height

In the given problem, the radius is equal to 4 m and the height is equal to 4 m.  Plugging these values into the equation:

V = π4²(4) = π16*4 = 64π m³
