Answer:
422 in.2
Step-by-step explanation:
Substitute the measurements of the rectangular prism into the formula SA = 2(lw) + 2 (lw) + 2(lh): 2(13)(7) + 2(6)(7) + 2(13)(6) = 422 in2.
Irrational numbers. √7 is an irrational number.
Answer:
V/(pi r^2) = d
Step-by-step explanation:
V = pi r^2 d
Divide each side by pi r^2
V/(pi r^2) = pi r^2 d/(pi r^2)
V/(pi r^2) = d
Then substitute the values into the equation to find d
