Given the area of a circle calculate the radius, circumference and diameter. Putting A, C and d in terms of r the equations are: Given the radius of a circle calculate the area, circumference and diameter. The area of a shape is measured in square units. Please point out that you are using the numerators of both fractions to divide it. Since each unit square occupies one square unit space, the total number of unit squares in the shape gives its area. clarify why you split the rectangle into 35 equal parts. Substitute the values of the length ly l y and width wb w b into. How to find the area of a rectangle using unit squares We can find the area of any two-dimensional shape by dividing that shape into smaller unit squares. Using the formulas above and additional formulas you can calculate properties of a given circle for any given variable. The area of a rectangle is equal to the length times the width. For circles, multiply the radius square by 3.14 (pi). For triangles, multiply the base by the height and then divide by 2. For rectangles and squares, multiply width by height. Step 4: Calculate the area of each shape using our Square footage calculator. Given any one variable A, C, r or d of a circle you can calculate the other three unknowns. The easy ones are Square and rectangle, circles and triangle could be a bit tricky. Alternatively, the formula to calculate the area of a rectangle is derived by dividing the shape into two equal size right triangles. Area of a rectangle length (l) × width (w) For example, if the length of a rectangle is 35 m and width is 25 m, then the area is 35 × 25 875 square meters. Use this circle calculator to find the area, circumference, radius or diameter of a circle. The formula for finding the area of a rectangle. Any other base unit can be substituted.Ĭircle Formulas in terms of Pi π, radius r, and diameter d Radius and Diameter: A area pi 3.1415926535898 square root Calculator Use. The units are in place to give an indication of the order of the results such as ft, ft 2 or ft 3. You can use it to find the surface area of the most common shapes. An easy to use, free area calculator you can use to calculate the area of shapes like square, rectangle, triangle, circle, parallelogram, trapezoid, ellipse, octagon, and sector of a circle. Units: Note that units of length are shown for convenience. In geometry, a rectangle is any quadrilateral with all. Given any one variable A, C, r or d of a circle you can calculate the other three unknowns. The Rectangle Calculator is used to calculate the area, perimeter and diagonal of a rectangle.
