Answerino:
yes, a 1:1 proportion
Given:
diameter = 14 inches
radius = 14 inches / 2 = 7 inches
Circumference of a circle = 2 π r = 2 * π * 7inches = 14 inches * π
Area of a circle = π r² = π * (7in)² = π * 49in²
C = 14π and A = 49π
The volume is 905.32 i believe
12(12)=144, 144(3.14)=452.16, 452.16(6)=2712.96, 2712.96/3=904.32
