How to Find the Surface Area of a Sphere: 8 Steps …
WebThe circumference of the cone's base=2πr, where r is the radius of the circular base's base. As a result, Curved surface area of cone (CSA) =1 2 ×l×2πr = πrl 1 2 × l × 2 π r = π r l. We know that a cone is made by rotating a right-angled triangle. Pythagoras Theorem helps us find the length of the slant side in a right-angled triangle ... WebNov 21, 2024 · Therefore, the hemisphere cap area equals: Ac = A (sphere) / 2, Ac = 2 × π × r². The base surface area is a circle with the same radius as a hemisphere. Thus, according to the circle calc: find A, it can be expressed as: Ab = π × r². Finally, the total surface area is the sum of those two contributions: A = Ac + Ab, how are cereal marshmallows made
