expand 2pi(81h-h^3)

Solution

expand

2 π (81 h - h^{3})

Solution

- 2 π h^{3} + 162 πh

Solution steps

2 π (81 h - h^{3})

Apply the distributive law:

a (b - c) = ab - a c

a = 2 π, b = 81 h, c = h^{3}

= 2 π 81 h - 2 π h^{3}

= 2 \cdot 81 πh - 2 π h^{3}

Simplify

2 \cdot 81 πh - 2 π h^{3} : - 2 π h^{3} + 162 πh

= - 2 π h^{3} + 162 πh
