17. The radius of a circular path is 7m. Find the cost of fencing the path if the cost per meter is Rs.35​
Elis [28]

The cost of fencing the path is Rs 1539.38.

It is required to find the cost of  fencing the path.

<h3>What is circle?</h3>

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.

Given that:

radius of a circular path is 7m.

Rate = Rs .35​ per meter

We know that

Circumference of circle =2\pi r

                                  2*\pi *7\\\\=43.98 m

Circumference of circle=43.98 m

Now,

Cost = Circumference × Rate

Cost =43.98× 35

Cost =  Rs 1539.38

Therefore, the cost of fencing the path is Rs 1539.38.

The missing side and angles are 16.8 , 23.33 degree and 123.7 degree respectively.

<h3>What is a Triangle ?</h3>

Triangle is a polygon with three sides , three angles and three vertices.

Given is triangle ABC , with sides  a = 8, c = 11, and m∠C=33 degree

The missing angle and side is given by Cosine rule of triangle

c² = a² + b² - 2ab cosC

11² = 8² + b²  - 2* 8 * b * cos 33

57 = b² -13.42 b

b²  -13.42b -57 = 0

b = 16.8

By sine rule

a / sin A = b/sin B = c/sinC

8 / sin A = 11 / sin 33

A = 23.33 degree

Similarly

B = 123.7 degree

Therefore the missing side and angles are 16.8 , 23.33 degree and 123.7 degree respectively.
