Please help me... i need it right now!
Just say the answer.. i don't need explanation.. but, don't say wrong answer... If you don't sure, then don't write anything!

Yo sup??

I guess the answer should be

=l²-πl²/4

=l²-0.783l²

=0.215l²

Hope this helps.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
