Question

The radius of a circle is 14 meters. What is the circle's area?
r=14 m
Use 3.14 for .

Answer 1

Area of a circle = pi * r^2

So in this case: (3.14) * (14)^2 = 615.44

Answer 2

The formula for the area of a circle:

`A = \pi r^(2)`

You have said:

`r = 14m`

So substitute the values of pi and r into the formula:

`A = \pi r^(2) \\A = (3.14)(14m)^(2) \\A = (3.14)(196m^(2) )\\A = 615.44m^(2)`
