Circle with an r

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: WebIn a circle with centre O and radius r, let OPAQ be a sector and θ (in degrees) be the angle of the sector. Area of the circular region is πr². Let this region be a sector forming an angle of 360° at the centre O. Then, the area of a sector of circle formula is calculated using the unitary method.
