Answer:
<h2><u><em>C. between 4.4 and 4.6</em></u></h2>Step-by-step explanation:
Because if you add 22 and 8 together you get 30 and once you get 30 you subtract 10 gaining 20 and then you divide 20 getting .
22+8= 30
30-10= 20
To find the standard equation for a circle centered at the origin, we use the distance formula, since the radius measures?
2 answers:
Answer: The answer is (a). the distance from any point in the circle to the origin.
Step-by-step explanation: We know that to find the standard equation of a circle centred at the origin, we always use the distance formula. We are to select the correct measurement for the radius from the options given.
In a circle, as shown in the attached figure, the radius 'r' is the distance from any point 'P' on the circle to the centre 'O' of the circle. The centre of the circle in standard form is usually the origin.
So, we can say that radius measures the distance from any point on the circle to the origin.
Thus, (a) is the correct option.
