Cross-section area of artery, A=πr2=3.14×(2×101)2A=\pi r^2=3.14\times(2\times10^{-1})^2

A=0.1256 cm2A=0.1256\space cm^2

Velocity of flow, v=40 cm/sv=40\space cm/s

Volumetric Flow rate, q=Av=0.1256×40=5.024 cm3/sq=Av=0.1256\times40=5.024\space cm^3/s

Volume passing through artery in 30s =qt=5.024×30=150.72 cm3=qt=5.024\times30=150.72\space cm^3
