Option B.
Step-by-step explanation:
Consider the below figure attached with this question.
From the below figure it is clear that the center of the given circle is (4,5).
The standard form of a circle is
where, (h,k) is center of the circle and r is radius.
We need to find the equation of a circle which represents the same center as the circle shown but with a radius of 2 units.
Substitute h=4, k=5 and r=2 in the above equation.
The required equation is .
Therefore, the correct option is B.
Answer:
outer edge of the island is 20.8 miles
Step-by-step explanation:
As shown in figure sailor spot two mermaids at point B and C. BC is the outer edge of island. Point A represents sailors
AD=6 miles is perpendicular bisector of BC.
It is clear that
and
we will find BD and DC
in
=
Similarly, in
=
Therefore outer edge of the island,
