Problem: What is the radius of the sphere given the surface area? Example: What is the radius of a sphere with a surface area of 900π? Show Video Lesson Problem: The surface area of a sphere is 5024 square meters. What is the volume of the sphere? Use 3.14 for pi. Round your ans...
As you can see the shape of a sphere has the lowest possible surface area to volume ratio and therefor requires the least energy to maintain its shape. The minimization of energy cost is usually what drives the physical world, hence natural objects like bubbles and raindrops tend to a spheri...

1.11.1 Surface-area-to-volume ratio The sphere is the shape that offers the minimum surface area for a given volume: volumeofasphere=43πr3or16πD3 When foods are heated in packages (cans, bottles or flexible pouches), it is desirable to maximize the surface-area-to-volume ratio; thi...
If the total surface area of a cube is 864 square cm, find the volume of the cube: (a) 1728 cm3 (b) 1624 cm3 (c) 144 cm3 (d) 1684 cm3 View Solution Find the volume and the surface area of a sphere of radius 3.5 cm.
<p>To find the volume of a sphere given its surface area, we can follow these steps:</p><p><strong>Step 1: Use the formula for the surface area of a sphere.</strong> The formula for the surface area \( A \) of a sphere is given by: \( A = 4\pi r^2 \) whe

12 The volume, V, and surface area, S, of a sphere of radius r are given by V=4/3πr^3 a nd S=4πr^2respectively.The volume of a sphere increases at a rate of 200 cm3 per second. At the instant when the radius of the sphere is 10 cm, find(i) the rate of increase o...
The surface area of a sphere with radius i in a graph is the number of nodes in the graph whose distance from a given node is exactly i. The volume of a sphere with radius i in a graph is the number of nodes within distance i from the given node. In this paper, we derive ...
