Acircle centered at the origin passes through the point (3, 5). what is the area of the circle to the nearest tenth of a square unit?

34.0 units2
106.8 units2
213.5 units2
none of the above

A = π(34), or approx. 106.8 units²

Step-by-step explanation:

Recall that the formula for the area of a circle is A = πr².

If  (3, 5) is a point on the circle at hand, then the radius (found using the Pythagorean Theorem) is r = √(3² + 5²) = √(9 + 25) = √34.

Then r² = 34, and the area of this circle is

A = π(34), or approx. 106.8 units²

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
