Answer:
Formula for the area of a circle;
A = π

Where 'π' represents pi(3.14 or 22/7), and 'r' represents the radius which is being squared.
Plug in the radius into this formula:-
A = π

- Note: I will be using 3.14 as pi(π).
A = 3.14(4^2)
A = 3.14(16)
A = 50.24 centimetres is the area for this circle.
