The yard of fabric that Melissa has is 6 inches squared since there are 36 inches in a yard and 6 times 6 is 36. The footrest has a surface area of 902 inches squared since the surface area of a rectangular prism is 2(lw+wh+lh).
Answer:
D.
Step-by-step explanation:
Simply plug in your variables and solve (<em>r </em>= x + 2 and <em>h</em> = 3x + 8):
V = π(x + 2)²(3x + 8)
V = π(x² + 4x + 4)(3x + 8)
V = π(3x³ + 20x² + 44x + 32)
V = 3x³π + 20x²π + 44xπ + 32π
