Question

Find the area of a circle with radius 6 in. Use the value 3.14 for π, and do not round your answer.

Answer 1

The area is:

113.04 in²

Step-by-step explanation:

To find the circle's area, use the formula
`\sf{A=\pi r^2}`.

where:

A = area;

π = 3.14 (pi);

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 6\ in}\end{picture}`

Plug in the data:

`\sf{A=3.14*6^2}`

`\sf{A=3.14*36}`

`\sf{A=113.04\:in^2}`

Answer 2

Step-by-step explanation:

Área of a circle is given as

`\pi * {r}^(2)`

Therefore you can substitute the values as follows:

`3.14 * {6}^(2) = 113.09733552923`

Answer not rounded to any decimal place and used of 3.14 as said in the instruction
