expand r(75-pir^2)

Solution

expand

r (75 - π r^{2})

Solution

- π r^{3} + 75 r

Solution steps

r (75 - π r^{2})

Apply the distributive law:

a (b - c) = ab - a c

a = r, b = 75, c = π r^{2}

= r \cdot 75 - r π r^{2}

= 75 r - π r^{2} r

Simplify

75 r - π r^{2} r : - π r^{3} + 75 r

= - π r^{3} + 75 r
