What is the circumference of a 10 inch diameter circle?
31.42cm
Since the diameter is 10cm, we know that C = π x 10cm = 31.42cm (to 2 decimal places).
What is the diameter of a circle of 10?
but you should use your calculator to get the most accurate results. If the circumference of the circle is 10 cm, then the diameter is 10 cm/π, or 3.18 cm. If you know the area of the circle, divide the result by π and find its square root to get the radius; then multiply by 2 to get the diameter.
How many inches is a 10 inch circle?
1 Answer. ≈79 square inches.
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.
How do you calculate circumference with diameter?
Write down the formula for finding the circumference of a circle using the diameter. The formula is simply this: C = πd. In this equation, “C” represents the circumference of the circle, and “d” represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.
How do you calculate the distance around a circle?
The circumference formula is used to calculate the distance around a circle. Circumference formulas: C = 2πr or C = πd. r is the radius and d is the diameter. The diameter is the longest chord that runs through the center of the circle.
