Lets work backwards. π r2 = 62 cm. 62 / 3.14 = 17.75. Square root of 17.75 = 4.21. Okay, now using the radius of 4.21 we will use the formula C = 2 πr. C = 2 (3.14)(4.21) = 2 (13.22) = 26.44. So the circumference of each button is approximately 26.44 cm.
The radius= 4.21 cm
The circumference of the circle is 26.44 cm.
we have given that
Area = 62 square centimetres.
What is the formula for the area of circle
[tex]A=\pi r^{2}[/tex]
A=62 and pi=3.14
[tex]62=3.14r^{2}[/tex]
find the value of r square divide both side by 3.14
[tex]r^2=\frac{62}{3.14}[/tex]
[tex]r^2=17.75\\[/tex]
[tex]r=4.21cm[/tex]
[tex]circumference of circle =2\pi r[/tex]
[tex]C=3.14)(4.21)\\\\C= 2 (13.22) \\\\C= 26.44.cm[/tex]
Therefore we get,
The radius= 4.21 cm
The circumference of the circle is 26.44 cm.
