Again, decimals and fractions represent all the values in between integers. Decimals are simply one step more of simplification from fractions.
Answer: 1,004.8 cubic meters (choice D)
Work Shown:
V = (1/3)*pi*r^2*h
V = (1/3)*3.14*8^2*15
V = 1,004.8
Answer:
correct
Step-by-step explanation:
The perimeter is the sum of the sides.
Rectangle ( opposite sides are congruent ), thus
perimeter = 2x + 2(x + 18) = 2x + 2x + 36 = 4x + 36
Square ( sides are congruent ), thus
perimeter = 4(x + 9) = 4x + 36
The perimeters are the same, so the student is correct
