1 using 2pir

Step-by-step explanation:

using area ok ok ok ok

Answer 2

Step-by-step explanation:

1. ( a )circumference of circle = 2 x π x radius

- circumference of circle = 2 x 3.14 x 4 = 25.12 m

( b ) circumference of circle if her diameter is = 18

we need radius for circumference so = radius - 18/2 = 9

circumference of circle = 2 x π x 9

= 2 x 3.14 x 9

= 56.52 m
