Answer:
B.
Step-by-step explanation:
Let S=larger square side and s=smaller square side. The area between the larger and smaller is simple the larger area minus the smaller area. The area of any square being s^2. So our remaining area is:
A=S^2-s^2
A=144-49=95 cm^2
Solving inequalities is almost the same as solving equalities for basic cases. Only thing you've to watch out for is signs.
For example, in 2x + 3 > 5,
We may subtract 3 from both sides,
2x > 2
Hence, by dividing both sides by 2, we get x>1.
The inequality sign changes on multiplying with (-)
For example, 2 < 6
But, -2 > -6
And when you interchange a fraction
E.g. 3/4 > 2/3
But, 4/3 < 3/2
You can now solve these of your own
Try yourself
You're starting at 400. Each time you're cutting in half.
So the common ratio is 1/2 which means the equation is
which is in the geometric sequence format. So the answer is choice D
Area=3.14(r)^2
radius is half of diameter
3.14(9.5)^2=283.385
rounded is 283.39
