The diameter of a circle has endpoints whose coordinates are r(-2, 2) and s(4, 2). what is the length of the radius?

3 units

Step-by-step explanation:

Using distance formula :

The diameter of the circle with endpoints  R(-2, 2) and S(4, 2) will be

Since, the radius of a circle is half of the diameter.

Then the radius of the circle will be

Hence, the radius of the circle = 3 units.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
