Question

Find the area of the circle diameter 14 ft. Use the value 3.14 for n, and do not round your answer

Answer 1

Since the diameter is 14ft, we can easily see that the radius is:

`r=(d)/(2)=(14)/(2)=7ft`

then, we can find the area with the following formula:

`A=\pi\cdot r^2`

in this case, we have the following:

`\begin{gathered} A=(3.14)\cdot(7)^2=3.14\cdot49=153.86 \\ \Rightarrow A=153.86ft^2 \end{gathered}`

thus, the area of the circle with diameter 14ft is 153.86ft^2
