For the one you put in the comment...
The radius of a circle is 19cm find its area in terms of π
A = π 
A = π 1
A = 361π
For the other one you put in the comment
The radius of a circle is 4 cm find its area in terms of π
A = π 
A = π 
A = 16π
For the other one you put in the comment
The radius of a circle is 20 cm find its area in terms of π
A = π 
A = π 
A = 400π
