The surface of a sphere is:
A=4? r2
From this, the surface are changes as the square of the radius. It does not change linearly.
When a cell doubles in diameter, the cell membrane surface area is multiplied by four. This is because the surface area of a sphere (or a cell in this case) is proportional to the square of its radius.
To calculate the surface area of a sphere, you can use the formula ( A = 4\pi r^2 ), where ( r ) is the radius. For a sphere with a radius of 7 meters, the calculation would be ( A = 4\pi (7^2) = 4\pi (49) = 196\pi ). Approximating (\pi) as 3.14, the surface area is approximately ( 615.44 ) square meters.
If the surface area of a spherical balloon increases by 11%, the radius will increase by approximately 3.3%. This relationship is based on the formula that relates surface area to radius in a sphere (Surface Area = 4πr^2).
To draw a great circle on a sphere, start by defining the diameter as the largest circle that can be drawn on the sphere's surface. For small circles, choose a point on the sphere and draw a circle with that point as the center and the radius less than the sphere's radius. Remember that the center of a small circle lies outside the circle on a sphere's surface.
No. The surface to volume ratio of a sphere is always smaller than that of a cube. This is because the sphere has the smallest surface area compared to its volume, while the cube has the largest surface area compared to its volume.
