Answer:
1386 cm²
Step-by-step explanation:
Given : -
Diameter ( d ) = 72 cm
The value of π = 22/7
To find : Area of a circle
We know that,
We know that,the Diameter of the circle = 2 x Radius ( r )
We know that,the Diameter of the circle = 2 x Radius ( r )d = 2r
42 = 2r
r = 42/2
r = 21 cm
r = 21 cmFormula : -
r = 21 cmFormula : -A = πr²
A = (22/7) * 21²
= (22/7) * 21 * 21
= (22 * 21 * 21)/7
= 22 * 21 * 3
A = 1386 cm²
Hence,
the Area of the Circle is 1386 cm².
