Question

Find the area of each circle with the give radius/diameter
please step by step explanation ​

Answer 1

Answer:

Step-by-step explanation:

a)radius=4.2

→radius of circle=4.2

therefore,circumference of circle= πr²

                                                     =  3.14 *4.2*4.2

                                                    =55.42

                                         

b)diameter=13

→circumference of circle=πr²

radius= d/2

         =13/2

          =6.5

3.14*6.5*6.5

=132.73

c diameter 24

radius=24/2

         =12

area of of circle = πr²

                          =22/7 *  12 ²

                       =452
