What is the radius of 40 cm?
You see the radius is 1/2 the diameter and 1/6 the size of circumference….Look at the table.
| Radius | Diameter | Circumference |
|---|---|---|
| 10cm | 20cm | 62.4cm |
| 20cm | 40cm | 124.8cm |
What is the diameter of a 40 in circle?
The diameter is 12.74.
How do you find the length of a radius in a circle?
Explanation: The radius is half of the diameter. To find the radius, simply divide the diameter by 2.
What is the radius of a circle the length of its diameter?
radius is always half the length of its diameter. For example, if the diameter is 4 cm, the radius equals 4 cm ÷ 2 = 2 cm.
How do you find the radius of 40?
1 Answer
- r = 402π
- r = 20π
- Therefore r = approx. 203.14159 = 6.37 inches.
Whats circumference if diameter is 40?
A circle has a diameter of 40 inches. What is the circumference? Write your answer using pi. I know the answer is 125.6, but I don’t have an idea of how to write it using pi.
What is the formula for diameter and radius?
The distance between the center of the circle to its circumference is the radius. The diameter is always double the radius. Hence, the formula is derived by dividing the diameter by 2….Formulas for Radius.
| Radius Formulas | |
|---|---|
| Radius in Terms of Circumference | C ⁄ 2π |
| Radius in Terms of Area | √(A ⁄ π) |
Is radius half the length of diameter?
A radius is half the length of the diameter.
What is the difference between diameter and radius?
Essentially, the diameter is twice the radius, as the largest distance between two points on a circle has to be a line segment through the center of a circle. The circumference of a circle can be defined as the distance around the circle, or the length of a circuit along the circle.
What determines the area of a circular field?
The circumference of the circular field determines the area of the field. Radius or diameter of the circle are the important factors for calculating the field area.
What is the formula to find the radius of a circle?
Formula: D = 2 × R Where, D = Diameter R = Radius
What are the dimensions of a circle in math?
Dimensions of a Circle. 1 The diameter – defined above. 2 The radius – the distance from the circle’s center or origin to the edge, one half the diameter. 3 The circumference – the length of the outside boundaries of the circle.
