A circular plate has circumference 21.4 inches. What is the area of this​ plate? Use 3.14 for pi.
Brut [27]

Answer:

The area of this plate is 36.31\ \text{inches}^2.

Step-by-step explanation:

We have,

Circumference of a circular plate, C = 21.4 inches

The circumference of a circular shape is given by :

C=2\pi r

r is radius of circular shape

r=\dfrac{C}{2\pi}\\\\r=\dfrac{21.4}{2\times 3.14}\\\\r=3.4\ \text{inches}

Area of this plate is given by :

A=\pi r^2\\\\A=\pi (3.4)^2\\\\A=36.31\ \text{inches}^2

So, the area of this plate is 36.31\ \text{inches}^2.
