Please help me! :) Evaluate the expression 3.14(a2 + ab) when a = 3 and b = 4.

3.14 [(3×2)+(3×4)]

3.14(6+7)

3.14×13

so the answer is 40.82

:) have a nice day

56.52

Step-by-step explanation:

You want to begin with plugging in a and b into the expression.

a=3

b=4

3.14(3(2)+3(4))

Then simplify

3.14(6+12)

3.14(18)=56.52
