![]() Substituting the value: A = π * (5 inches)² ≈ 78.54 square inches. Question: Calculate the area of a circle with a radius of 5 inches.Īnswer: The area (A) of a circle is found as A = πr², where "r" is the radius. Substituting the values: V = 6 meters * 8 meters * 10 meters = 480 cubic meters. ![]() ![]() Question: Determine the volume of a rectangular prism with dimensions 6 meters, 8 meters, and 10 meters.Īnswer: The volume (V) of a rectangular prism is given by V = length * width * height. Question 3: Volume of a Rectangular Prism Substituting the value: C = π * 14 cm ≈ 43.98 cm. Question: Find the circumference of a circle with a diameter of 14 centimeters.Īnswer: The circumference (C) of a circle is calculated as C = πd, where "d" is the diameter. Question: Calculate the perimeter of a regular octagon with a side length of 9 inches.Īnswer: The perimeter of a regular octagon is found by multiplying the side length by 8 (the number of sides). The circumradius of an isosceles trapezoid is the radius of a circle that circumscribes the trapezoid, meaning that it passes through all vertices (corners) of the isosceles trapezoid.Question 1: Perimeter of a Regular Octagon The formula for calculating the diagonal of an isosceles trapezoid is: In every isosceles trapezoid there are two diagonals of equal length. The formula for calculating the perimeter of an isosceles trapezoid is:Ī diagonal of an isosceles trapezoid is a line segment that connects two non-adjacent vertices. The perimeter of an isosceles trapezoid is the sum of the lengths of all its sides. The area of an isosceles trapezoid is the region enclosed inside the trapezoid. If you know the two bases and the circumference: If you know all sides of the isosceles trapezoid: It can be calculated with the following formulas: The height of an isosceles trapezoid is the perpendicular distance between the two parallel sides. Then you can use one of the following formulas: To calculate the leg length, you need to know the length of the long base, the short base and one other value. They also form two equal angles at the end of each parallel side. The legs of an isosceles trapezoid are the two sides that are equal in length and connect the parallel sides (bases). If you know the leg length and perimeter: ![]() Then you can calculate the second base with one of the following formulas: To calculate all the values of an isosceles trapezoid, you need to know the value of at least one of the base sides and two other values. You can calculate the second base with one of the following formulas: To be able to calculate all values of an isosceles trapezoid, you must know the value of at least one of the base sides. In our case, the long side (a) is the bottom base and the short side (b) is the top base of the trapezoid. These two sides are known as the bases of the isosceles trapezoid. The long and short sides are the two sides that are parallel to each other. There are eight parts of an isosceles trapezoid mentioned in this tool: long side (a), short side (b), legs (c), height (h), area (A), perimeter (P), diagonal (d) and circumradius (R). If the legs are also parallel to each other, then we get a parallelogram. The two parallel sides are called bases, and the other two sides are called legs. An isosceles trapezoid (or trapez) is a trapezoid with legs that have equal length.Ī trapezoid is a geometric shape with four sides, where at least one pair of sides is parallel to each other.
