Question

circumference of circular sheet is 154 m. find its radius. also find the area of the sheet​

Answer 1

Answer:

Take pi = 22/7

Step-by-step explanation:

Circumference = 154 m

2 pi r = 154

2*22/7*r = 154

2*22/7*r = 154

r = 154*7/2*22

* = times

Answer 2

Area of the sheet = 24.5 cm

Step-by-step explanation:

The circumference of a circle is the distance between one point to another point of the circle. In other words it is a perimeter of shapes such as squares. For the shapes is straight edge is called perimeter whereas if the line is circular it is called the circumference.

According to question,

given, circumference = 154 cm

find radius of a circle = ?

by using formula to find radius

circumference of circles =

                                         $2\pi r=154$

                                         $2\times\frac{22}{7}\times r=154$

                                         $44r=154\times 7$

                                          $r=\frac{154\times7}{44}$\

                                          $r=3.5\times7\\r=24.5 cm$
