<span>if it takes 1 and </span>3<span>/4 </span>cups<span> to </span>make<span> 1 batch how </span>many cups will<span> it take to </span>make 2<span> and 1/</span>2 <span>batches. 4.375 </span>cups<span> = x. You </span>can<span> also </span>add<span> the </span>cups<span> one batch and then a half batch at a time. 7/4 + 7/4 + (7/4*1/</span>2<span>) = x. multiply the first </span>two<span> (7/4) by </span>2/2.<span> Then you </span>have<span> 14/8 + 14/8 + 7/8 = 35/8 = 4.375 </span>cups<span>.</span>
She would have 480$. If you multiply 8 x 15 your will get 120. You than multiply 120 x 4.
Hey there!
Our formula for cylinder area is:
π

h , with r being the radius and h being the height.
When we plug in our values, we get:
A =

A = π(144)(13)
A = 1872π

Therefore, your answer is
B, 1872.Hope this helps!
