Question

Q:-16/The circumference of a circle is 4x cm Find the area of the circle.​

Answer 1

Answer:

(4x²) / (pi) cm²

Step-by-step explanation:

given, the circumference of the circle = 4xcm

ie., 2(pi)r = 4x cm

r = 2x/(pi)

therefore, the area is given by (pi) r² sq.units

=> (pi) *(2x/(pi))*(2x/(pi)) cm²

=> (4x²) / (pi) cm²
