The area of the top surface of wedge shaped cheeses bought by Mai is 39.3 cm².
The area of a circular sector is the total space occupied by it. The sector area is half of the product of the square of radius of the circle and the central angle.
The complete question is...
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? *
Given: central angle = 45 degrees
radius = 10cm
Now,
Area of the top surface =
Area of a sector = (θ/360) * πr²
= 45/360 * 3.14* 10*10
=1/8* 314
= 39.2857
= 39.30 cm²
