It's 3x+2 because 3 ÷2 is 6 so it's 3x+2
Answer:
439.6 inches
Step-by-step explanation:
The distance apart cna be obtained using the formular :
Number of revolutions = 7
Diameter, d = 20 inches
π * number of revolutions * diameter
3.14 * 7 * 20
= 439.6 inches
You must do 1/2 times base times height
Volume of prism = area of base * height
= area of triangle * height
(in this case triangle)
Volume = ( 0.5*13*13)*7
= (84.5)*7
= 591.5
answer is C
