WebSep 21, 2024 · If a circle has radius less than one, does it mean that the circumference of the circle is bigger than the area? How can that even be possible? For example, if a circle has radius 0.5, then the circumference is 2 π ⋅ 0.5 = π, and the area will be π ⋅ 0.5 2 = 0.25 π. How can this be the case? circles area paradoxes Share Cite Follow WebSo radians are the constant of proportionality between an arc length and the radius length. It takes 2\pi 2π radians (a little more than 6 6 radians) to make a complete turn about the …
Ensuring a non-zero radius when constructing a circle
WebNov 4, 2024 · C = 0.10πr 2 + 0.12πrh Then, substitute the volume formula into the cost formula to get the cost formula in terms of r. C = 0.10πr 2 + 0.12πr (400/πr 2) C (r) = 0.10πr 2 + 48πr -1 Now just set dC/dr = 0. You will use first derivative test. Solve for r to get your minimum radius. WebApr 30, 2024 · Intuitively, I guess the answer should be yes because otherwise, we can construct the osculating circle at c ( t 0). But if r is the radius, we would have r = 1 / κ ( t 0) which is impossible for κ ( t 0) = 0. If that is true, is there an easy way to make this argument more formal? differential-geometry curves curvature plane-curves Share Cite i posted one
