<span>We have to calculate the length of the missing side.
Use the Pythagorean theorem:

a^2+32^2=58^2\\\\a^2+1024=3364\ \ \ |-1024\\\\a^2=2340\to a=\sqrt{2340}\\\\a=\sqrt{36\cdot65}\\\\a=6\sqrt{65}

\cos x=\dfrac{6\sqrt{65}}{58}=\dfrac{3\sqrt{65}}{29}

I think. Your answers to choice are wrong.

Pls answer I will give brainliest
Levart [38]

Answer: 108 ft³ 

Step-by-step explanation:

V= 4/3πr³ 

Facts:

Pi= 3

Diameter = 6

Step1; find the radius

Diameter is the length acaross the whole circle, but the radius is just 1/2 the circle. Therefore, if the diameter is 6, then the radius can be found by finding 1/2 of 6.

1/2 of 6= 1/2x6= 3.

R= 3

Step 2:  Plug in the numbers (into the formula)

PEMDAS

(exponents go first)

(then multiply from left to right)

V= 4/3πr³ 

V= 4/3x3x3³ 

V= 4/3x3x (3x3x3)

V= 4/3x3x27

V= (4/3x3)  x 27

V= 12/3x27

V= 4x27

V= 108

<u><em>Volume= 108 ft³ </em></u>

<u><em></em></u>

Hope this helps :)) Also brainliest would be appreciated, i worked pretty hard on this thanks! :)
