Answer:
b) 516.2 cm³
Step-by-step explanation:
1) We can break the figure into two parts, a rectangular prism and a half cylinder.
2) The volume of the rectangular prism can be determined by multiplying 12 × 7 × 5, which is 420.
3) The equation for the volume of a cylinder is πr²h, but since this is half a cylinder, we will need to use the equation 1/2 × πr²h.
4) 1/2 × π × 3.5² × 5. The radius is 3.5, because the diameter is 7.
5) This should give us 30.625π.
6) Now we add 30.625π + 420, which is approximately 516.2.

Answer:
No
Step-by-step explanation:
2*37 equals 74
(2*3)*7 is a different case. You first have to do what is inside the parentheses. 2*3 is 6. 6*7 equals 42. You wouldn't distribute in this case, because of the multiplication position and PEMDAS.
