Answer:
0.4444444
Step-by-step explanation:
It is important to note that the perimeter is equal to 2(width) + 2(length). let's call width w and length L.
so 294 = 2w + 2L
but the length is two times the width, so L=2w.
294 = 2w + 2(2w)
294 = 2w + 4w
294 = 6w
divide both sides by 6 to solve for w.
49 = w. so our width is 49 feet.
L = 2w, so L = 2(49). L = 98.
our length is 98 feet.
your calculations for volume (pi x r^2 × h) and surface area (2 × pi × r (h+r)) are correct. However your ratio are incorrect. From the formulas the ratio of surface area to volume would be r×h:2(h+r)
Answer:
c
Step-by-step explanation:
it has to be a negative graph so a and d aren't right and the y intercept is 3 so c is right
