Polygons are multi-sided shapes with different ... The perimeter of a 2D shape is the total distance around the outside of the shape. The area of a 2D shape is the space inside the shape.
Polygons can be regular or irregular. If the angles are all equal, and all the sides are equal in length, it is a regular polygon. To find the sum of interior angles in a polygon, divide the ...
Calculate the surface area of the glass. A cone is the general name of a shape that has a flat base of any shape tapering up to a point. The base can be any shape: if it is a polygon the shape is ...
The sides of the rectangle are therefore h and 2Ï€r. The area of each of the two circles is \(\pi r^2\)and the area of the rectangle is \(2 \pi r \times h\). The surface area of a cylinder is the ...
