When Mrs. Stewart makes pie dough, she uses 2/3 cup of shortening for every 2 1/2 cups of flour which proportion could be used t
n200080 [17]

Answer:

She will use the ratio shortening to flour as 4 : 15

Step-by-step explanation:

When Mrs. Stewart makes pie dough, she uses \dfrac{2}{3} cups of shortening for every 2\dfrac{1}{2} = \dfrac{5}{2} cups of flour.

So, for each \dfrac{2}{3} cup of shortening she uses \dfrac{5}{2} cups of flour.

Then, the ratio of shortening to flour in the mixture of pie dough will be  

\dfrac{\dfrac{2}{3} }{\dfrac{5}{2} } = \dfrac{4}{15} i.e. 4 : 15.

Therefore, she will use the ratio shortening to flour as 4 : 15 to find the amount of flour she needs when she uses 5 cups of shortening. (Answer)

9514 1404 393

Answer:

  • 262.2π cm²
  • 392.16π cm²

Step-by-step explanation:

The lateral surface area is the product of half the circumference, and the slant height:

  LA = πrh = π(11.4 cm)(23 cm) = 262.2π cm²

The total surface area adds the area of the base to that:

  A = πr² +LA = π(11.4 cm)² +262.2π cm² = (129.96 +262.2)π cm²

  A = 392.16π cm²
