Where A = the area of a circle. pi (π) = 22/7 or 3.14 and r = the radius of a circle. Let’s get a better understanding of this formula by working out a few example problems. Example 1 Find the area of a circle whose radius is 15 mm....
The area of a circle is the region or space measured inside the circle, or the total number of square units inside the circle. Calculating the area of a circle is not as straightforward as calculating the area of a square, for example, because of the object's shape. A circle may also...
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. ...
Area problems can be solved by breaking the area up into known geometric shapes. The area of each of the known shapes can be calculated by using their formulas, and then all the answers can be added to get the final answer. What is an example of an area problem? An example of an ...
Area of a Sector Examples Example 1: If the angle of a sector of a circle is 60°, and the radius of the circle is 7 inches, what is the area of the sector of this circle? Solution: The radius of the circle is 7 inches and the angle is 60°. So, let us use the area of ...
Area of a ShapeA shape is defined as a figure enclosed by a boundary. We see uncountable objects around us in shapes such as square, rectangle, circle etc. Now, what is this area of shape? Let’s dive deeper into the concept.The area of shape is the space enclosed within the ...
Circle Area = c² / 4π Also, the circle area formula is handy in everyday life – like the serious dilemma of which pizza size to choose. Sector area formula The sector area formula may be found by taking a proportion of a circle. The area of the sector is proportional to its ang...
The circle with centre (h, k) and radius r has the equation: (x − h)2 + (y − k)2 = r2These formulas are a direct result of Pythagoras' Formula for the length of the hypotenuse of a right triangle.Example 1Sketch the circle x2 + y2 = 4.Find the center and radius first...
