Answer:
D
Step-by-step explanation:
The area of a circle can be found using:
a=πr^2
We know that the radius is 10 meters. Therefore, we can substitute 10 in for r.
a=π*10^2
Evaluate the exponent
a=π*100
Multiply pi and 100
a=314.159265359
Round to the nearest tenth: there is a 5 in the hundreth place, which indicates we round up the 1 in the tenths place to a 2.
a=314.2
The area is 314.2 square meters, or choice D

Step-by-step explanation:
Answer:
Point slope form : 
Slope intercept form: 
Standard form : 
Step-by-step explanation:
From the given graph it is clear that the line is passing through the points, (-4, 0), (-2, 1), (0, 2), and (2, 3).
If a line passes through two points
and
, then the equation of line is

Let as consider any two points of the line: (2, 3) and (0, 2).
The equation of line is


The point slope form of the line is
.


Add 3 on both sides.


Therefore the slope intercept form of the line is
.
Multiply both sides by 2.


Therefore, the standard form of the line is
.
