WebOct 31, 2024 · For a circle with radius r, a square with the same area will have a side length of r√π. So, for example, if a given circle has a radius of 10 cm, then a square with the same area as the circle will have a side length of 10√π cm. Alternatively, we can also convert a given square to a round shape by doing the reverse operation.

I was using some previous answers found here, but it is not working. st_buffer shows an error. WebMar 9, 2024 · r = 4t. I'm going to assume that the initial length of the radius at time 0 is 0, since it's not specified in the problem. From this, we can figure out the time t when the radius is 1: 1 = 4t. t = 1/4. Now, let's look at area. The formula for the area of a circle is: A = π r 2. We can rewrite this as a function of t since we know r=4t from above: WebJan 8, 2024 · Calculate the arc length according to the formula above: L = r * θ = 15 * π/4 = 11.78 cm.
