What is the equation of the circle with center (1, 1) that passes through the point (−3, 4)?
Alex_Xolod [135]

Answer:  (x - 1)² + (y - 1)² = 25

<u>Step-by-step explanation:</u>

The formula for a circle is     (x - h)² + (y - k)² = r²     where

  • (h, k) is the center
  • r is the radius

Typically, you are given the center and the radius.  In this problem, you are given (x, y) so you must plug that into the equation to find r².

Given: (x, y) = (-3, 4)   and   (h, k) = (1, 1)

                       (-3 - 1)² + (4 - 1)² = r²

                         (-4)²    +   (3)²   = r²

                          16      +    9     = r²

                                  25         = r²

Next, input (h, k) and r² into the equation

                  (x - 1)² + (y - 1)² = 25

If the volume of a cube is 64 cm3, then the side length is 4 cm, because 4x4x4 = 64.

If the side length is 4cm, then the area of one side is 16cm2, and the surface area is 96cm2
