Question

Find the area of the circle. Use 3.14 for pie. Do not round your answer.

and inside the circle it says 14 inches

Answer 1

The area is:

615.44 in²

Work/explanation:

The formula for the area of a circle is:

`\sf{A=\pi r^2}}`

Where

A = area

π = 3.14

r = radius

Diagram:

`\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\qbezier(2.3,0)(2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,-2.121)(0,-2.3)\qbezier(2.3,0)(2.121,-2.121)(-0,-2.3)\put(0,0){\line(1,0){2.3}}\put(0.5,0.3){\bf\large 14\ in}\end{picture}`

Plug in the data:

`\sf{A=3.14*14^2}\\\\\sf{A=3.14*196}\\\\\sf{A=615.44\:in^2}`

Hence, the area is 615.44 in².

Answer 2

given:

radius= 14 inches

to find:

the area of the circle.

solution:

`area = \pi {r}^(2)`

`a = \pi * {14}^(2)`

`a = 615.75216`

`a = 615.75 \: {in}^(2)`

therefore, the area of the circle is 615.75 square inches.
