What is the circumference if the radius is 4 cm?
8π
The circumference is 8πcm or 25.12cm .
What is the circumference if diameter is 4cm?
4π cm
It is usually measured in units, such as cm or unit m. Since the diameter is known to us, we can calculate the radius of the circle. Therefore, Circumference of the circle is 4π cm.
What is the circumference of 4 radius?
8 π
Answer: The circumference of a circle with a radius of 4 is 8 π.
What is circumference of a 4 circle?
The circumference of a circle is given by. c=πd. Where c is the circumference, π is a number and its approximate value is 3.14 and d is its diameter. ⇒c=π4=3.14⋅4=12.56 inches.
How do you find a circumference?
To find the circumference of a circle, multiply the circle’s diameter by pi (3.14).
How do you find the circumference of a 4 inch radius?
Answer: The circumference of a circle with a radius of 4 is 8 π. The circumference of a circle is its boundary or the length of the complete one of a circle. Explanation: Calculate the circumference of a circle is by using the formula 2 π r, where r is the radius of the circle.
What is the diameter of 4 radius?
For example, if the diameter is 4, the radius would be 2. Check your calculations for accuracy. Work through your results backward to verify your findings. Use “D = R x 2”, in which “D” equals diameter and “R” equals radius, to solve for the diameter using the numbers you got earlier.
What is the diameter of a 4 circle?
Circumferences and areas of circles with diameters in inches.
| Diameter (in) | Circumference (in) | Area (in2) |
|---|---|---|
| 4 1/8 | 12.96 | 13.36 |
| 4 3/16 | 13.16 | 13.77 |
| 4 1/4 | 13.35 | 14.19 |
| 4 5/16 | 13.55 | 14.61 |
What is the area of radius 4?
16π sq. units
Answer: The area of the circle with a radius of 4 units is 16π sq. units.
How do you find circumference with radius?
The perimeter or circumference of the circle can be found using the equation C=2π(r), where r= the radius of the circle. Since we have two semi-circles we can find the circumference of one whole circle with a radius of 4, which would be 8π.
How do you convert radius to circumference?
To calculate the circumference, you need the radius of the circle:
- Multiply the radius by 2 to get the diameter.
- Multiply the result by π, or 3.14 for an estimation.
- That’s it; you found the circumference of the circle.
What is the circumference of the radius is 4?
