Question

Use 3.14 as pi.
Alex wants to cut out as many circular badges as possible from this rectangular sheet of cardboard. the diameter of each badge is 14 cm. how many badges can he cut?

Answer 1

First, we need to find the area of each circular badge using the given diameter:

Radius = diameter/2 = 14/2 = 7 cm
Area of a circle = pi x radius^2
Area of a badge = 3.14 x 7^2 = 153.86 cm^2

Next, we need to find the total area of the rectangular cardboard sheet:

Length = ?
Width = ?
Area of rectangle = Length x Width

Unfortunately, we don't have enough information to find the length and width of the cardboard sheet. We can't solve the problem with the given information.
