Diameter Formula :
If d be the diameter of the circle, then its circumference be (π × d) units.
Given that :
d = 20 cm
So, circumference of the circle
= π × 20 cm
= 440/7 cm [π = 22/7]
Radius Formula :
If r be the radius of the circle, then circumference of the circle is (2 × π × r) units.
Given that, diameter = 20 cm.
So, radius = diameter/2 = 10 cm
Thus, circumference of the circle
= 2 × π × 10 cm
= 440/7 cm [π = 22/7]

Area of the circle
= π × (radius of the circle)²
= π × 10² cm²
= 100π cm²
= 2200/7 cm² [π = 22/7]
