Heya !!!

Here is your answer,

=================================

Given : -
diameter of a circle = 14 cm

As we know
diameter = 2×r ( 'r' is "radius" )

=> diameter/2 = r

=>14/2 = r

=> 7 cm = radius

=================================

Circumference of the circle = 2πr
= 2×22/7×7
= 44cm

=================================

Area of the circle = πr²
= 22/7×(7)²
= 22/7×49
= 154 cm²

=================================

Hope it helps.
