Answer: The sum of the interior angles of a polygon shown in the picture is .
Step-by-step explanation:
The given polygon is a regular pentagon having 5 sides.
The sum of the interior angles of a regular polygon is given by :-
, wherer n= number of sides of the regular polygon.
Since it has 5 sides, then the sum of the interior angles of a polygon would be
Hence, the sum of the interior angles of a polygon shown in the picture is .
Answer:
175.84 m
Step-by-step explanation:
Given that:
A circular garden which has a radius of 28 m.
= 3.14
To find:
The fencing required to enclose the circular garden ?
Solution:
Here, we are given a circle and its radius.
We are required to find the perimeter of the circle in order to find the fencing required to enclose the circular garden..
Formula for finding the perimeter of a circle is:
Perimeter =
where is the radius of the circle.
Using the given values in the formula:
Perimeter = = <em>175.84 m</em>
Therefore, 175.84 m of fencing is required.
