Please help me it’s 10 points also this is my first time on this app
Given :
Dimension of table :
5000 mm * 3600 mm
Area of rectangle = Length * width
Area of table = 5000 * 3600
Area of table = 18000000 mm²
Recall :
1 cm = 10 mm
Diameter of circular plate = 10cm
Converting to mm :
10 * 10 = 100 mm
Area = diameter/ 2 = 100 mm / 2 = 50 mm
Area of a circle = πr²
Area of circular plate = 3.14 * 50² = 7850 mm²
Number of plates = 18000000 / 7850
= 2292.9936 plates
About 2293 plates
