Circumference of a circular cylinder
WebAug 2, 2024 · 3. 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. This goes back to manipulating the formula for finding the area of a circle, A = πr 2, to get the diameter. You can transform this into r = √ (A/π) cm. [3]

WebSep 28, 2024 · Multiply the circumference of the circle by the height of the cylinder. This will give you the outer edge surface area. Multiply the circumference, 18.84 centimeter …
WebSo 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 leverage pi r squared to figure out that the radius was 6, and then from that we were able to figure out that the circumference ... WebThe surface area of a cylinder refers to the total area that the cylinder's curved surface and circular bases cover. ... In the rectangle, one side is the height of the cylinder h, while the length of this rectangle is the circumference of the circle, that is, 2πr. Thus, the area of this rectangle (l × b) is = 2πr × h = 2πrh which is also ...
WebFeb 17, 2024 · So, to find the volume and surface area, we need the radius and the height of the cylinder. Since the radius is half of the diameter, we can just divide 18 by 2, so the …
