Question

Find the area of the circle.

Use 3.14 for T.
O
d = 12 ft
A = [?] ft²
A = πr²

Answer 1

113.04ft²

Explanation:

`Here,\\\hookrightarrow d=12ft\\\hookrightarrow r=d/2=12ft/2=6ft\\Now,\\\hookrightarrow Area=\pi r^(2) \\\hookrightarrow Area=3.14 * (6ft)^(2)\\\hookrightarrow Area=113.04ft^(2)`

Answer 2

Hi, there!

_______

Start by dividing the diameter by 2 to find the radius:

`\mathsf{12/2=6}`

Now substitute 6 into the formula

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

`\triangleright\sf{A=\pi 6^2}`

`\triangleright\sf{A=36\pi }`

{remember to use 3.14 for π}

`\triangleright\sf{A=113.04 \ feet^2}`

Hope the answer - and explanation - made sense,

happy studying!!
