Question

the radius of a circle is 12cm .find its circumference and area (
$(\pi = 3.14)$

Answer 1

Given
radius of circle=12 cm
circumference= 2πr
=2*3.14*12
=75.36 cm
Area = π r^2
= 3.14*12*12
= 452.16 cm^2
hope this helps you mate........

Answer 2

Hey here is your answer....

Circumference =2 pi r
Therefore,
Circumference =2×3.14×12
=24×3.14
=75.36cm
Since, area=pi r^2
Therefore,
Area=3.14×12^2
=3.14× 144
=452.16cm^2

HOPE IT HELPS YOU!!!
