WebA sector of a circle is essentially a proportion of the circle that is enclosed by two radii and an arc. Given a radius and an angle, the area of a sector can be calculated by multiplying the area of the entire circle by a ratio of the known angle to 360° or 2π radians, as shown in the following equation: area =. θ. 360. WebArea and Perimeter. Area and Perimeter are very important terms while dealing with mathematics. This applies to any shape of the field, irregular or regular. The perimeter is the distance around the object. For example, your house has a fenced yard. The perimeter is the length of the fence. If the yard is 50 ft × 50 ft your fence is 200 ft long.

WebFeb 15, 2024 · Both area and perimeter are two dimensional in nature. Each geometry has a unique area and perimeter of its own. Formulas can be derived to find the area and perimeter of various geometries. Area is expressed in terms of square units and perimeter is expressed in terms of units. WebCalculating the area and the perimeter. Do excercises Show all 2 exercises. Area - Rectangle Area and perimeter The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. WebApr 11, 2024 · Here are some solved examples based on the area and perimeter formulas of different shapes. Example 1: If the radius of a circle is given as 7cm. Find its area and circumference. Solution: Given that radius = 7cm. We have, Area A = π × r2. A = 22/7 × 7 × 7. A = 154 cm2. And Circumference, C = 2πr. C = 2 x 22/7 x 7. field roofing services
