Question

Fiona draw a circle with a diameter of 14 meters. What is the area of Fiona circle?

Answer 1

153.938 meters

Explanation:

The area of a circle is Pi * (Radius)^2. The radius is the diameter/2.

14/2=7

Pi * (7)^2

153.938 m

Answer 2

154 cm^2

Explanation:

`d =14\\Area = \pi * r^2\\r = d/2\\r = 14/2\\r= 7\\A = 22/7 * 7^2\\(22)/(7) * 49\\Simplify\\(22)/(1) * 7\\Area =154`

`A =(1)/(4) \pi * d^2\\A = (1)/(4) * (22)/(7) *14^2\\A = 1/4*22/7*196\\A = 154cm^2`
