<h2>~<u>Solution</u> :-</h2>
If we take the radius of a circle be <u>R</u>. Then, we can define that,
$ R = x $
Hence,
Arcs will be as $ 4x $. As,
A circle can be divided into four parts according to the radius.
Hence, we know that,


- Hence, <em>according to the radius R</em>, a circle can have <u>4 arcs</u>.
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:
-a will be greater than -b because for example, when a=2 and b=5, -a=-2 and -b=-5
The answer would be C. 5(5) + 2(2) = 29
(5) + 4(2) = 13
