Since a hemisphere is half of a sphere, its surface area, S, is half the surface area of a sphere plus the area of the circular base (shown in gray) created by intersection of the plane and sphere: S = 4πr 2 /2 + πr 2 = 3πr 2. where r is the radius of the hemisphere.

Process 1: Note down the sphere volume from the question. Divide 3 times of volume by 4 times of π. Calculate the cube root of the result to check the radius. Process 2: Find the sphere circumference. Divide the circumference by 2 times π. The obtained value is known as the radius of a sphere. Process 3:The minimum surface area of a sphere is calculated using the formula A = 4πr², where A is the surface area and r is the radius of the sphere. 3. Why is the minimum surface area of a sphere important? The minimum surface area of a sphere is important because it represents the most efficient use of surface area for a given volume.

surface area of a sphere gives us just such an answer. We’ll think of our sphere as a surface of revolution formed by revolving a half circle of radius a about the x-axis. We’ll be integrating with respect to x, and we’ll let the bounds on our integral be x 1 and x 2 with −a ≤ x 1 ≤ x 2 ≤ a as sketched in Figure 1. x1 x2 So, the circumference of a sphere can also be computed as 6.28 times or 44/7 times its radius. Total Surface Area of Sphere. The total surface area of a sphere is the same as its curved surface area because the sphere does not have any lateral surfaces. The formula obtained by deriving surface area of a sphere is written Mathematically as: …

In the above example, the radius of the sphere is 8 cm. If the diameter is given, divide the diameter by 2 to get the radius. Step 2: Now, surface area of sphere = 4 π r 2, so after substituting the value of r = 8, we get, surface area of sphere = 4 π r 2 = 4 × 3.14 × 8 2 = 4 × 3.14 × 64 = 803.84. Step 3: The problem is that the expression with spherical unit vectors does not take into account the coordinates of the point. In other words, $\hat n=(1,0,0)$ for every $(r,\theta,\phi)$. So, my second approach was calculate it via parametrization of the sphere.In today’s fast-paced world, cognitive abilities play a crucial role in our everyday lives.
