The length of the circle with the radii of 6.5 cm and 3.5 cm. Which circle is longer and by how much?
| June 20, 2021 | education
The circumference is calculated by the formula 2pR, where R is its radius.
Using the formula, we find the length of the first circle:
2 * 3.14 * 6.5 = 40.82 (cm).
Find the length of the second circle:
2 * 3.14 * 3.5 = 21.98 (cm).
Let’s find how much the first circle is longer than the second:
40.82 – 21.98 = 18.84 (cm).
