expand pih(4r^2-h^2)

Solution

expand

πh (4 r^{2} - h^{2})

Solution

4 πh r^{2} - π h^{3}

Solution steps

πh (4 r^{2} - h^{2})

Apply the distributive law:

a (b - c) = ab - a c

a = πh, b = 4 r^{2}, c = h^{2}

= πh \cdot 4 r^{2} - πh h^{2}

= 4 πh r^{2} - π h^{2} h

π h^{2} h = π h^{3}

= 4 πh r^{2} - π h^{3}
