What is the radius of a circumference of 13?
The radius is 2.07 ft.
What is the radius of a 13 circle?
∴ , the radius is 132 units or 7.5 units.
Can you find radius from circumference?
To find the radius from the circumference of a circle, you have to do the following: Divide the circumference by π, or 3.14 for an estimation. The result is the circle’s diameter. Divide the diameter by 2.
What is the radius of 12 circumference?
The formula for the circumference of a circle is C = 2πr, so the circumference of this circle can be represented by C = 2π(12). This simplifies to C = 24π. If we use 3.14 for π, then C = 24(3.14) = 75.36 inches.
How do you find the radius of a circle with the diameter?
Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet.
What is the circumference of a 3/4 inch diameter circle?
Circumference & Areas
| Size in Inches | Circumference Inches | Area in Square Inches |
|---|---|---|
| 1/2 | 1.571 | 0.250 |
| 3/4 | 2.356 | 0.563 |
| 1 | 3.142 | 1.000 |
| 1 1/4 | 3.927 | 1.563 |
What is the circumference of a 12 inch circle?
To find the circumference of a circle, you will use the formula C=2⋅π⋅r ; therefore the circumference C is 2⋅π⋅6≈38 inches.
What is the radius of a circle in feet?
The radius is 2.07 ft. Circumference is the perimeter of the circle. Diameter is the distance across the circle going through the center of it. Radius is half the diameter. Pi is a very useful number used for measurements of circles all the time, however since it seems to never end I will round it to 3.14.
What is the circumference of a circle?
The circumference of a circle is pi times its diameter. The diameter of a circle is the distance from one edge to the other, passing through the center. It is twice the radius.
