Answer:
18 square units
Step-by-step explanation:
area = full square units + 1/2 x half- full square units
full square units = 12
half- full square units = 12
= 12 + (1/2 x 12)
=12 + 6
=18 square units
Given:
The point (7, 4) lies on a circle centered at the origin.
To find:
The equation of the circle and the radius of the circle.
Solution:
Distance formula:
The point (7, 4) lies on a circle centered at the origin. So, the distance between the points (7,4) and (0,0) is equal to the radius of the circle.
The standard form of the circle is
...(i)
Where, (h,k) is the center of the circle and r is the radius of the circle.
Putting h=0, k=0 and in (ii), we get
Therefore, the equation of the circle is and its radius is .
The term axiom is used to describe statements that is taken to be true and can not be proofed. The axioms are taken as the most true statements (more true than theorems and conjectures) and are used as a starting points for other proofs and argumentation. Proof is <span>the sufficient evidence for the truth of a statement. So, in order to obtain a proof several true statements (axioms) must be used. </span>
