expand pirh(r+h)

Solution

expand

π r h (r + h)

Solution

πh r^{2} + π h^{2} r

Solution steps

π r h (r + h)

= πh r (r + h)

Apply the distributive law:

a (b + c) = ab + a c

a = π r h, b = r, c = h

= π r h r + π r hh

= πh rr + πhh r

Simplify

πh rr + πhh r : πh r^{2} + π h^{2} r

= πh r^{2} + π h^{2} r
