Answer:
Step-by-step explanation:
Given that,
y varies directly as x. It means,
y = kx
Where
k is the constant of variation
or
So, the constant of variation is .
In any circle of radius R, how many arcs with lengths R fit into the circumference?
1 answer:
<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 formula you have given here is for the volume of a cylinder. It should read 
.
First, to find r, the radius, divide the diameter by two (since the radius is the distance from the circumference to the centre and the diameter is the distance from any point on the circumference to the opposite point (through the centre))
r = 8/2 = 4
Now we can calculate this.
If your answer needs to be in litres, one cubic centimetre = one millilitre.
603 cm3 = 603mL = 0.603 L
