What is the circumference of a 5 inch circle?
C=2×π×2.5. inches or 2π2.5. inches ⇐ This is the exact circumference. C=2×π×2.5in≈15.7in ⇐ This is an approximate circumference because it is rounded off.
How do u find the circumference of a circle?
To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π=3.14).
What is the formula for finding the circumference of a circle?
To calculate the circumference of a circle, use the formula C = πd, where “C” is the circumference, “d” is the diameter, and π is 3.14. If you have the radius instead of the diameter, multiply it by 2 to get the diameter.
What is the approximate circumference of a circle?
Explanation: If you are looking for an approximate answer, it means we can just do a quick estimate. The circumference of a circle is found by multiplying the diameter of a circle by π. The value of π is about 3.142, but for an estimate we can just use 3. For a diameter of 7, the circumference will be a bit more than 3 times 7.
What is the radius of a circle with the diameter of 6?
For example, a circle with a diameter of 6 inches has an approximate circumference of 18.84 inches. If you only know the radius of the circle, the formula “2 times pi times the radius” can be used. A circle with a radius of 15 inches has a circumference of 2 X 3.14 X 15 inches = about 94.2 inches.
How do you find the area of a circle with circumference?
The area of a circle is given by the formula A = π r 2, where A is the area and r is the radius. The circumference of a circle is C = 2 π r.
