Step-by-step explanation:
Answer:
13,363.84 square cm
Step-by-step explanation:
For this question,
The circle table has a radius of 56 cm and the height of the edge of the cloth is 10cm(height) below the tabletop, which is a rectangle
We need to find out the area of a circle, Then the area of the rectangle.
Area of circle FORMULA= πr^2 | Area of rectangle FORMULA = l * h
πr^2
3.14 * 56 * 56 = area of circle = 9,847.04
[(2*3.14*56)Perimeter of circle which is also length of rectangle] * 10 = area of rectangle = 3516.8
9,847.04 + 3516.8 = 13,363.84
