Olivia bakes a rectangular cake that is 7 1⁄2 inches wide, 12 inches long and 2 1⁄4 inches high. If Judy frosts each side of the cake, what is the surface area of the cake she needs to frost?

133.875 inches

this is because you multiply 7 1/2 times 12, 7 1/2 times 2 1/4 and, 2 1/4 times 12 t get your answers if the surface area, 133.875 as a decimal, 1071/8 as a improper fraction, and 133 7/8 as a mixed fraction.

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4
