Several different cheeses are for sale. The cheese comes in wedges shaped like sectors of a circle. All of the wedges are the same height.

10a. Mai bought a wedge with a central angle of 45 degrees and radius 10

centimeters. What is the area of the top surface of this wedge? *

39.30

Step-by-step explanation:

The area of the top surface of the wedge is the same as the area of a sector.

Area of a sector = (θ/)

where: θ is the central angle, and r is the radius.

Given that: central angle = , radius = 10 centimetre.

Area of the top surface = Area of a sector = (θ/)

                                      = x x

                                      = x x 100

                                      = 39.2857

                                     = 39.30

The area of the top surface of the wedge is 39.30 .
