Answer:

Step-by-step explanation:
we know that
The general form of the equation of a circle is

where D, E, F are constants
step 1
Find the radius of the circle
Remember that the distance from the center to any point on the circle is equal to the radius
so
the formula to calculate the distance between two points is equal to
substitute the values
step 2
Find the equation of the circle in standard form

In this problem we have
center ( -2,1)
radius r=2 units
substitute


Step 3
Convert to general form

Answer:
The distance between the two points, (3, -7) and (3,5) is 12
Step-by-step explanation:
PLEASE MARK BRAINLIEST
New length: 5×3=15 in.
New width: 3×3=9 in.
New height: 2×3= 6 in.
V=l×w×h
V=15×9×6
V= 810 cubic inches. Hope it help!
The question given here has two parts and each part has to be answered separately. In case of both the multiplications, the answer might look to be huge but by applying a simple technique, anybody can do these multiplications without the help of any calculator.
Now let us take the case of first multiplication that is given:
50000 * 700
= 35000000
In this case all the zeroes present has to be written first and then 7 and 5 should be multiplied and put. This will get the answer easily.
Now we take the second multiplication given:
100 * 123478
= 12347800
In this case also the zeroes are simply put on the right side of the number 123478.
