Question

How do I find the circumference and the area of a circle with a diameter of 6 cm while using the value 3.14 without rounding my answer??

Answer 1

then it is just 6pi, because pi is infinite

Answer 2

Circumference = 18.84cm

Area = 28.26cm^2

Explanation:

Circumference of a circle

= 2pi r

Pi = 3.14

Radius r = diameter/2 = 6/2 = 3

Therefore

Circumference = 2 x 3.14 x 3

= 18.84cm

Now, area of a circle = pi r2

r = 3 cm

Pi = 3.14

Area = 3.14 x 3^2

= 3.14 x 3 x 3

= 28.26cm^2
