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.
