Answer:

  • Radius is 1 unit

Step-by-step explanation:

<u>The relationship is:</u>

  • V = πr²h

<u>We have points on the graph:</u>

  • (9, 28.26) and (18, 56.52)

<u>Use one of the points, substitute into equation and solve for r:</u>

  • 28.26 = 3.14*9*r²
  • r² = 28.26/28.26
  • r² = 1
  • r = 1
