We will now look at the formula for the area of a sector where the central angle is measured in degrees. Recall that the angle of a full circle is 360˚ and that the formula for the area of a circle is πr2. Comparing the area of sector and area of circle, we derive the formul...

The utility model relates to a circle area calculating demonstration apparatus. The utility model is composed of a demonstration block and a demonstration plate which are provided with magnetic devices. The utility model is convenient for a teacher to teach children the derivation of the formula pi...
Surface area of cone = Area of sector + area of circle =πrs + πr2 =πr(r + s) Surface area of a cone when given the slant height Example: A cone has a circular base of radius 10 cm and a slant height of 30 cm. Calculate the surface area. ...

We defined the efficiency as the ratio of the light energy inside a circle of radius of three times the full width half maximum (FWHM) at the focal spot over the total energy in the focal plane. With increasing NA, the FWHM decreases, making the efficiency improvement lower with increased ...
Theheightof the cylinder is the perpendicular distance between the two bases. The net of a solidcylinderconsists of 2 circles and one rectangle. The curved surface opens up to form a rectangle. Surface area = 2 × area of circle + area of rectangle ...
Here’s an image of three waypoints with “500 meter” buffers: The reason I put “500 meter” in quotes is that buffers are usually defined by the distance from the periphery, which would mean in this case that the circle radius would be 500 meters. But the actual radius is only 250...
