WebThe area of a rectangle is length x width. In this case, length = the height of the cylinder and width = the circumference of the end of the cylinder (the circle). The length is given, and the width can be calculated using the formula for circumference of a circle. WebNow let's fit a cylinder around a sphere . We must now make the cylinder's height 2r so the sphere fits perfectly inside. The volume of the cylinder is: π × r2 × h = 2 π × r3. The volume of the sphere is: 4 3 π × r3. So the sphere's … WebJan 7, 2016 · The angle around the sphere's equator is the texture's u coordinate. atan2 gives us that angle. Assuming y is the vertical (north-south) axis of your globe. Otherwise swap y and z in the formula if z is the vertical axis in your sphere's coordinate system. – Stephane Hockenhull Jan 7, 2016 at 13:12 Add a comment 0 Leaving this here for myself: how to check real download speed
