What is the area of circle with a radius of 13 milimeters? use 3.14 for pi

530.66mm²

Step-by-step explanation:

Area of a circle =

r(radius) = 13mm

Area = (3.14 × 13²)mm²

        = (3.14 × 13 × 13)mm²

        = (3.14 × 169)mm²

        = 530.66mm²

Hope this helps :))

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
