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.
