Question

What will be the ratio of the numbers giving the measurement of the circumference and area of ​​a circle of radius 3 cm​

Answer 1

Answer:

circumference of circle is 2pie r = 2 × 22/7 × 3 = 18.85

Answer 2

Answer:

2:3

Explanation:

if,

r= 3

then,

circumference=2πr

=2×π×3

=6×π

Area=πr^2

=π×3^2

=π×9=9×π

So, ratios are,

→ Circumference:Area

=6×π:9×π

=6:9 (cancel out π)

=2:3

Hence, ratio is 2:3
