Question

perimeter of cube
perimeter of cone
perimeter of sphere​

Answer 1

• A cube, though, can be viewed as a collection of two-dimensional objects, since each of its six faces is a square. Just as the square's perimeter is the sum of its four individual sides, the perimeter of a cube is the total of all of its separate sides, also known as the cube's edges. A cube has 12 identical edges.

• The perimeter of the base of a cone is 44 cm and the slant height is 25 cm. Find the curved surface of the cone. Hint: To find the curved surface of the cone, we are given the perimeter of the base of a cone which is the same as the circumference of a circle, that is, C=2πr.

• The Circumference of a circle or a sphere is equal to 6.2832 times the Radius. The Circumference of a circle or a sphere is equal to 3.1416 times the Diameter.
