What is the circumference of a 5cm diameter circle?
Circles (basic)
| Diameter | Circumference | Approx. |
|---|---|---|
| 10 cm | 31.4 cm | 10cm X 3 = 30 |
| 2 cm | 6.24 cm | 2cm X 3 = 6 |
| 5 cm | 15.7 cm | 5cm X 3 = 15 cm |
What is the circumference of 6 cm diameter?
12π cm
Finding the Circumference: If r = 6 cm, the the circumference is c = 2π(6) = 12π cm, if writing in terms of π. If you prefer a numerical value, the answer rounded to the nearest tenth is 37.7 cm.
Can you get circumference from diameter?
Multiply the diameter by π, or 3.14. The result is the circle’s circumference.
What is the area of a 5cm circle?
R2 (radius squared) means radius × radius. Therefore a circle with a radius of 5cm has an area of: 3.142 × 5 × 5 = 78.55cm2.
What is the radius of this circle 5cm?
r = 0796 is right answer.

How is Dia calculated?
How To Calculate Diameter?
- Diameter = Circumference ÷ π (when the circumference is given)
- Diameter = 2 × Radius (when the radius is given)
- Diameter = 2√[Area/π] (when the area is given)
