I) The circumference of a circle is 4π. Find the area of the circle.
Answers
Circumference of a circle is given as 4π.
✳ Formula for Circumference of a circle = 2πr.
⟹
2πr = 4π
⟹
\sf r = \dfrac{4\pi }{2\pi }r=
2π
4π
⟹
r = 2 units (∵ We are not provided with the unit).
AREA OF THE CIRCLE
Area of a circle = πr²
Now,let us substitute the values of r = 2 and π = 3.14 in the above equation.
∴Area of the circle = 3.14 × 2²
⟹
Area of the circle = 3.14 × 4
⟹
Area of the circle = 12.56 Square Unit (∵ We are not provided with the unit).
Answer:-
Area of the Circle of circumference 4π = 12.56 Square Unit.
