expand Dr(pir^2+ar)

Solution

expand

Dr (π r^{2} + a r)

Solution

π D r^{3} + D a r^{2}

Solution steps

Dr (π r^{2} + a r)

Apply the distributive law:

a (b + c) = ab + a c

a = Dr, b = π r^{2}, c = a r

= Dr π r^{2} + Dr a r

= π D r^{2} r + D a rr

Simplify

π D r^{2} r + D a rr : π D r^{3} + D a r^{2}

= π D r^{3} + D a r^{2}
