what is the formula of perimeter of semicircle?
14118
The perimeter of a semicircle is half of the circle. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) or πr, where r is the radius.

A quarter circle is one fourth of a circle. To find the area of a quarter circle, find the area of the whole circle by using the formula A = pi * r^2 and then divide by 4. To find the perimeter of the quarter circle, find the circumference of the whole circle, divide by 4, and then add the radius twice.

The perimeter of the major segment = 2r[sin Ɵ+ π- πƟ/180]. Case 4: If the radius of the circle = r and the chord is at a distance = d from the centre of the circle; then the perimeter of the minor segment = 2√(r^2-d^2)+(2πr/180)*arc cos (d/r).

This would be the perimeter of a rectangular prism formula: Perimeter of rectangle: 2l + 2w where l is the length of the rectangle and w is the width. Apply standard perimeter calculations to the base shape of the prism, and that gives you the perimeter.

To find the perimeter, add together the lengths of the sides. Start at the top and work clockwise around the shape. Area of Polygon = (Area of A) + (Area of B) To find the area, divide the polygon into two separate, simpler regions.

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.

Multiply the length of one side of a regular polygon by the number of sides to find its perimeter. Regular polygons have identically sized sides. For example, if the shape is a regular pentagon, which has 5 sides, with a side length of 4 inches, then multiplying 4 inches by 5 results in a perimeter of 20 inches.

The perimeter of a rectangle is the distance around it. The formula for finding perimeter is P = l + w + l + w or P = 2 l + 2 w. Students can find the missing side using the perimeter and the known side. Students need to remember that there are two sides that have the same length or width.
