![\frac{7^{16} }{7^{12} }= \frac{7^{16-34} }{7^{12-34} } =\frac{7^{-18} }{7^{-22} } = 2401](https://tex.z-dn.net/?f=%5Cfrac%7B7%5E%7B16%7D%20%7D%7B7%5E%7B12%7D%20%7D%3D%20%5Cfrac%7B7%5E%7B16-34%7D%20%7D%7B7%5E%7B12-34%7D%20%7D%20%3D%5Cfrac%7B7%5E%7B-18%7D%20%7D%7B7%5E%7B-22%7D%20%7D%20%3D%202401)
so the missing term in the denominator is 7^(-22)
ok done. Thank to me :>

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
