Answer:
Step-by-step :-
Step 1 :
given,
Circumference of the circular plate, C = 27.6 inches
Area of the circular plate, A = ?
Step 2 :
Formula :-
C = 2πr ( r is the radius of the circular plate )
27.6 = 2*3.14*r (here π = 3.14 )
6.28*r = 27.6
r = 27.6/6.28
r = 4.39 inches
Step 3 :
Formula :-
A = πr^2
= 3.14*(4.39)^2
= 3.14*19.27
= 60.51 square inches
Therefore, the area of the circular plate is 60.51 square inches.
