$\dfrac{3960}{7}=565.2 \space cm^3$
Formula to calculate the volume of a right circular cylinder is: Volume, $V=\pi r^2 H$ ...(1) Given: $d=6 \space cm$ and $H= 20 \space cm$ As we know $r=\dfrac{d}{2}$ Thus, $r=3 \space cm$ From equation (1), we have Volume, $V=\pi r^2 H$ Volume, $V=\dfrac{22}{7} (3)(20)=\dfrac{3960}{7}=565.2 \space cm^3$
