Marcus made a mistake in Step 2. 5/2.5 is 2 not 3.
-11 -(-42) A double negative makes a positive
-11 + 42
31
Answer:
2 miles
Step-by-step explanation:
Because I said so

Actually Welcome to the Concept of the Surface Areas and Volumes.
Since, Volume of cone = 1/3 π r^2 h,
here, r = 10 Inches and h= 12 inches, also π =3.14
so, VOC = 1/3 π (10)^2 × (20)
VOC = 1/3(3.14)(100)(20)= 2093.33 inch^3
=> so the volume of the cone is 2093.33 cubic inches.
Direct variation is of the form y=kx (inverse variation is of the form y=k/x)
672 dollars is the net price because 15 percent off of 10 percent of 662 dollars is about 10 dollars and 10 + 662 is 672
