Answer:
<h2>20 cm.</h2>Step-by-step explanation:
We know that the permiter is defined as
Where is the longest side,
is the smallest and
is the middle side.
If then,
, where we need to find an expression for
using the law of cosines.
Replacing all expression, the perimeter is
Using a calculator, the perimeter is 20 units centimeters.
Solution:
As we given that
then using this conversion factor we can write
and further it can be written as
Hence the required conversion factor is 2.54 cm/1 inch as we can see from the above calculation.
Given:
Circumference of a circle = C
Diameter of a circle = d
To find:
The relationship between the circumference, c, and diameter, d, of any circle.
Solution:
We know that, circumference of a circle is
It can be written as
On dividing both sides by d, we get
Therefore, the correct option is (F).
