WebMar 21, 2024 · Example 3: Find the circumference of a circle whose diameter is 14 cm. Solution: Given: Diameter of the circle =14 cm. ⇒ Circumference of the Circle= π D = … WebSo if we take the principal root of 36, we get r is equal to 6. From there, we can use this to figure out the circumference. So the circumference is equal to 2 pi r. Circumference is equal to 2 pi r. And in this case, r is equal to 6. So it's equal to 2 pi times 6, which is going to be equal to 12pi. So that's straightforward, area 36pi, we ...
