Answer:
D. 76
Step-by-step explanation:
200x5%=10
300x7%=21
500x9%=45
10+21+45=76
4 x + 30 = 5x + 20
-5x -5x
-x + 30 = 20
-30 -30
- x = -10
x = 10
Based on the area of the tabletop with the inner circle, the area after the inner circle has been cut out is 12,309 inch².
<h3>How do we find the new area of the tabletop?</h3>
We are told that the area of the tabletop is 12,463 inch².
We then need to find the area of the circlular cutout as:
= π x radius x radius
= 3.14 x 7 x 7
= 154 inch²
The new area after the cutout is removed is therefore:
= Current area - area of circular cutout
= 12,463 - 154
= 12,309 inch ²
Rest of the question:
Area of table including the cutout is 12,463 square inches.
