Ответ:
=2πrh
=2π(8)(16)
=256π
End areas
=2πr²
=2π(8²)
=128π
Total surface area
=lateral area+end areas
=256π+128π
=384π

Step-by-step explanation:
Given that:
Fraction of pies =
of the total bakes goods
And the rest are cakes
Let total number of baked goods in the Bakery =![x](/tpl/images/1031/8891/a0e3f.png)
As per question statement, pies =![\frac{3}5x](/tpl/images/1031/8891/31ef0.png)
Amount of cakes =![x -\frac{3}{5}x = \frac{2}{5}x](/tpl/images/1031/8891/19c23.png)
Fraction of coconut =![\frac{1}{3}\times \frac{3}5x = \frac{1}{5}x](/tpl/images/1031/8891/74c90.png)
Fraction of angle food =![\frac{1}{6}\times \frac{2}5x = \frac{1}{15}x](/tpl/images/1031/8891/9c619.png)
a) What fraction of all of the baked goods are coconut pies.
This fraction can be found by dividing the fraction with the total amount of baked goods.
So, the answer is:
b) What fraction of all of the baked goods are angle food.
This fraction can be found by dividing the fraction with the total amount of baked goods.
So, the answer is:
