expand 2pir(r+7)

Solution

expand

2 π r (r + 7)

Solution

2 π r^{2} + 14 π r

Solution steps

2 π r (r + 7)

Apply the distributive law:

a (b + c) = ab + a c

a = 2 π r, b = r, c = 7

= 2 π rr + 2 π r \cdot 7

= 2 π rr + 2 \cdot 7 π r

Simplify

2 π rr + 2 \cdot 7 π r : 2 π r^{2} + 14 π r

= 2 π r^{2} + 14 π r
