उत्तर
The diameter of a circle is of length 6 cm. If one end of the diameter is (−4, 0), the other end on x-axis is at (2, 0).
Explanation:
Given that,
Length of diameter of circle = 6 cm
One end of diameter = (−4, 0)
Other end of diameter on x-axis will be of the form (x, 0)
Using distance formula,
→ `sqrt((x − (−4))^2 + (0 − 0)^2)` = 6
→ x + 4 = 6
→ x = 2
So, the other end of diameter is (2, 0).
