expand 2pirh(r-h)

Solution

expand

2 π r h (r - h)

Solution

2 πh r^{2} - 2 π h^{2} r

Solution steps

2 π r h (r - h)

= 2 πh r (r - h)

Apply the distributive law:

a (b - c) = ab - a c

a = 2 π r h, b = r, c = h

= 2 π r h r - 2 π r hh

= 2 πh rr - 2 πhh r

Simplify

2 πh rr - 2 πhh r : 2 πh r^{2} - 2 π h^{2} r

= 2 πh r^{2} - 2 π h^{2} r
