Answer:

Step-by-step explanation:

3) diameter of penny = 19 mm

                          r = 19/2 = 9.5 mm

Area of penny = πr²

                        = 3.14 * 9.5 * 9.5

                         = 283.385

                         = 283.39 mm²

Diameter of nickel = 21 mm

                          r = 21/2 = 10.5 mm

Area of nickel  = πr²

                         = 3.14 * 10.5 *10.5

                        = 346.185

                        = 346.19 mm²

346.19 - 283.39 = 62.8 mm²

Area of Canadian nickel is greater than Canadian penny by 32.6 mm²

4)  r = 12 mm

Area of circle = πr²

                      = 3.14 * 12 * 12

                       =  452.16 mm²

5) r  = 20 cm

Area of circle =  πr²

                      = 3.14 * 20 * 20

                      = 1256 cm²

Question 6(Multiple Choice Worth 3 points)
Marianna [84]
<h3>Answer:</h3>

A net is shown with 3 rectangles attached side by side all with width 2 centimeters. The length of the first and third rectangle is 9 centimeters and the middle is 7 centimeters. Attached to the middle rectangle below are 3 rectangles with a length of 7 centimeters. The width of these rectangles are 9 centimeters, 2 centimeters, and 9 centimeters.

<h3>Step-by-step explanation:</h3>

The area of a rectangular prism is the area of 6 surfaces. That is, 3 pairs of surfaces. Each of the three pairs will have one of the sets of dimensions ...

  • length × width
  • length × height
  • width × height

In order for a net to be a net useful for calculating the prism surface area, it must have 3 pairs of rectangles with these dimensions. The description above matches that requirement.

___

Please note that no two surfaces with the same pair of dimensions are adjacent.
