Answer:

fourth option

Step-by-step explanation:

Using the sine and cosine ratios in the right triangle and exact values

sin60° = \frac{\sqrt{3} }{2} , cos60° = \frac{1}{2} , then

sin60° = \frac{opposite}{hypotenuse} = \frac{x}{4\sqrt{2} } = \frac{\sqrt{3} }{2} ( cross- multiply )

2x = 4\sqrt{6} ( divide both sides by 2 )

x = 2\sqrt{6}

---------------------------------------------------------

cos60° = \frac{adjacent}{hypotenuse} = \frac{y}{4\sqrt{2} } = \frac{1}{2} ( cross- multiply )

2y = 4\sqrt{2} ( divide both sides by 2 )

y = 2\sqrt{2}

Answer:

r=5.4

As mentioned above, the actual \goldE{\text{total quantity}}total quantitystart color #a75a05, start text, t, o, t, a, l, space, q, u, a, n, t, i, t, y, end text, end color #a75a05 is 1000-10=\goldE{990}1000−10=9901000, minus, 10, equals, start color #a75a05, 990, end color #a75a05 grams, since we are trying to find the volume of the air within the shell.

Let's denote the ball's radius as rrr. Then, the \maroonD{\text{volume}}volumestart color #ca337c, start text, v, o, l, u, m, e, end text, end color #ca337c is \maroonD{\dfrac43\pi r^3}
