To change a decimal to a fraction, we simply "use as many zeros as there are decimals and lose the dot".
say in this case, 0.8 has 1 decimal, so we'll use one zero at the bottom,
A triangle has 3 sides....each side measuring 0.75 inches...and the perimeter is the total of all 3 sides.
0.75(3) = 2.25 inches
S A = r² π + 2 r π h
192 π = r² π + 2 r π h / : π
192 = r² + 2 r h
2 r h = 192 - r²
h = (192 - r² ) / 2 r
V = r² π h = r² π ( (192 - r² ) / 2 r ) =
= π / 2 ( 192 r - r³ )
