Answer: D.
Step-by-step explanation: Once you subtract from both sides, in order to solve for y (as the equation needs to be in the slope-intercept form, otherwise known as
), you end up with
, which is the right answer. It is the correct answer because the y-intecept shown in the equation matches what is on the graph, in addition to the fact that the slope is just
.
Answer:
Therefore it is possible to find the circumference and area of a circle if we are given the radius or diameter of the circle.
Step-by-step explanation:
i) to find the area of a circle or circumference the radius , r, is required.
ii) if we are given the diameter, d. then we have to find the radius, r, by dividing the diameter by 2, that is .
iii) area of the circle is given by A =
iv) circumference of the circle is given by C =
Therefore it is possible to find the circumference and area of a circle if we are given the radius or diameter of the circle.
