What is the diameter of the circle: x^2+y^2=16 ?

Mathematics

Answer:

<u>The diameter of this circle is equal to 8</u>

Step-by-step explanation:

The standard form of a circle is equal to x^2 + y^2 = r^2. As this equation shows x^2 + y^2 = 16, all we have to do is find the square root of 16, which is 4. This means that 4 is the radius of the circle and that 2 * 4 = 8, which is the diameter of the circle.

<u>Because of this, the diameter of this circle is equal to 8.</u>

State if the three sides lengths form an acute, obtuse, or right triangle: 7 in, 11 in, 13 in a acute b obtuse c right
xxTIMURxx [149]

Answer:

The triangle with side lengths 7 in, 11 in, 13 in will be an acute angled triangle.

Step-by-step explanation:

If we assume that the triangle with height 7 inches and base 11 inches of a right triangle then its hypotenuse will have the length of

\sqrt{7^{2} + 11^{2}} = \sqrt{170} = 13.04 inches.

But the third side of the triangle is given to be 13 inches which is less than 13.04 inches i.e. 13 < 13.04.

Therefore, the triangle with side lengths 7 in, 11 in, 13 in will be an acute-angled triangle. (Answer)
