Square the radius: 10^2 = 100 square feet. Multiply the result by pi, which equals approximately 3.142: 3.142 x 100 =

**314.2**. This answer is the circle's linear footage. A theoretical single board with a 1-foot width would need to be about 314 feet long to equal the circle in area.

Moreover, how many linear feet are in a 30 foot circle?

94.25ft

804.25 | square feet |
---|---|

115,812 | square inches |

74.717 | square meters |

747,171 | square centimeters |

Also Know, what is the circumference of a 7 foot circle?

So multiply that radius by 2, and then multiply the result by π to get the **circle's circumference**. If the radius of your **circle** is 3 **feet**, for example, its diameter is 3 × 2 = 6 **feet**; and the **circumference** is then 6 × 3.14 = 18.84 **feet**, or 6 × 3.1415 = 18.849 **feet** if you're asked for a more exact answer.

A **circle** is 360° all the way around; therefore, if you divide an arc's degree **measure** by 360°, you find the fraction of the **circle's** circumference that the arc makes up. Then, if you multiply the **length** all the way around the **circle** (the **circle's** circumference) by that fraction, you get the **length** along the arc.
