The area of a square can be calculated by using this formula:
![A=s^2](https://tex.z-dn.net/?f=A%3Ds%5E2)
Where "s" is the length of a side of the square.
In this case, you can identify that:
![s=9.7ft](https://tex.z-dn.net/?f=s%3D9.7ft)
Then, in order to estimate the area of the square, you can follow these steps:
1. Round the length "s" to the nearest whole number. Since the first digit after the Decimal point is 7 and:
![7>5](https://tex.z-dn.net/?f=7%3E5)
You must round up:
![s\approx10ft](https://tex.z-dn.net/?f=s%5Capprox10ft)
2. Knowing that:
![10^2=10\cdot10](https://tex.z-dn.net/?f=10%5E2%3D10%5Ccdot10)
You can determine that:
![A\approx100ft^2](https://tex.z-dn.net/?f=A%5Capprox100ft%5E2)
Hence, the answer is: Option C.
Answer:
The center of this circle is at
. The radius of this circle is
.
Step-by-step explanation:
A circle with center
and a radius of
(
) could be expressed as:
.
(In other words, a point is on this circle if and only if the distance between that point and the center is equal to the radius.)
Rearrange this equation using binomial expansion to match the equation given in this question:
.
.
The equation in this question is:
.
Match up the coefficients of
and
in the two equations.:
- Coefficient of
:
. - Coefficient of
:
.
Thus,
and
.
The constants of the two equations should also match up:
.
Substitute in
as well as
and solve for
:
.
(since
.)
Therefore, the center of this circle is
. The radius of this circle is
.
