Step-by-step explanation:

$\frac{y}{20 \sqrt{3} } = \sin(30)$

$y = 20 \sqrt{3} \times \frac{1}{2}$

$y = 10 \sqrt{3}$

$\frac{x}{20 \sqrt{3} } = \cos(30)$

$x = 20 \sqrt{3} \times \frac{ \sqrt{3} }{2}$

$x = 30$

option D, x=30 and y = 10√3

Which expression represents the volume, in cubic units, of the shaded part of the sphere? four-thirdsπ(103) four-thirdsπ(43) fou

oee [108]

The volume of the shaded part in cubic units is 4/3π(20)³ - 4/3π(4)³

<h3>Volume of composite object</h3>

The sphere is a a solid 3-dimensional object. THe formula for calculating its volume is expressed as:

V = 4/3πr³

where:

r is the radius of the sphere

<u>For the outer sphere:</u>

V = 4/3π(20)³

<u>For the inner sphere:</u>

V = 4/3π(4)³

The volume of the shaded part in cubic units is 4/3π(20)³ - 4/3π(4)³

Answer:

See belolw

Step-by-step explanation:

$P=53\text{ft}$

$P = a+b+c$

$53=2x-15+x+1+3x-29$

$53=6x-43$

$96=6x$

$x=16$

$a=2x-15$

$a=2(16)-15$

$\boxed{a=17}$

$b=x+1$

$b=16+1$

$\boxed{b=17}$

$c=3x-29$

$c=3(16)-29$

$\boxed{c=19}$
