A circle can be defined as, it is the locus of all points equidistant from a central point. In this we discuss about Properties of circle, circle formulas
Sector Area = ½ × r2×θ r = radiusθ = angle in radians Note: h is at right angles to b Example: What is the area of this rectangle? The formula is: Area = w × h w = width h = height We know w = 5 and h = 3, so: Area = 5 × 3 = 15 Example: What is...
Asectoris the area bounded by any two radii and the circle’s edge. How to Find the Radius of a Circle You canfind the radius of a circleusing one of the following formulas. Given the Diameter The radius of a circle is equal to half the circle’s diameter. The following formula defin...
The net of a solidconeconsists of a small circle and a sector of a larger circle. The arc of the sector has the same length as the circumference of the smaller circle. Surface area of cone = Area of sector + area of circle =πrs+ πr2= πr(r+s) ...
