Question

A circular plate has circumference 27.6 inches. What is the area of this​ plate?

Answer 1

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.
