Question

The area of circular plot is 154 cm2 . Find its circumference

Answer 1

Answer:

Step-by-step explanation:

area

=pi r^2

=154cm

22/7 * r^2 = 154

r^2 = 154 * 7/22

     = 7*7

r  = 7 cm

circumference = 2 pi r

                        = 2*22/7*7

                        = 44cm

Answer 2

Answer:

area of circle =154cm²

πr²=154

22/7×r²=154

r²=154×7/22

r²=7×7

r=7cm

circumference of circle=2πr

=2×22/7×7

=2×22

=44cm
