What is the equation of a circle with a center located at (-3, 4) and a diameter of 14?
AnnZ [28]

Answer: (x + 3)^2 + (y - 4)^2 = 49

Step-by-step explanation:

The equation of a circle given the center and radius: (x - h)^2 + (y - k)^2 = r^2

Given: center (-3,4) ; h = -3 and k = 4

diameter = 14

To find the radius: divide the diameter by 2 = 14/2 = 7 = r

Center: (-3,4) and radius: 7

Equation of a circle: (x - h)^2 + (y - k) ^2 = r^2

Substitute h = -3, k = 4, r = 7

(x - (-3))^2 + (y - 4)^2 = 7^2

Answer:

Equation of the circle: (x + 3)^2 + (y - 4)^2 = 49

Which special version of the Pythagorean Theorem can you use to find the length of any square's diagonal, d, using only the leng
kodGreya [7K]
The square's diagonal is the triangle's hypotenuse.

the original Pythagorean theorem is  a^{2} +  b^{2} = c^{2}   where a and b are the two sides and c is the hypotenuse.

that means the Pythagorean theorem for this question is:

s^{2} + s^{2} = d^{2}  or 2( s^{2} )= d^{2}
