Answer:

1172. 08 in²

Step-by-step explanation:

Hi there !

A(prism) = 2(lw + lh + wh) - Ab(cylinder)

= 2(16*11 + 16*11 + 11*11) - πr²

= 2(176 + 176 + 121) - 3.14*16

= 2*473 - 50.4

= 946 - 50.24

= 895.76 in²

A(cylinder) = πr² + 2πr*h

= 3.14*16 + 2*3.14*4*9

= 50.24 + 226.08

= 276.32 in²

A(total) = 895.76in² + 276.32in² = 1172.08 in²

Good luck !

a meal at a restaurant cost $49.28. If the customers leave $8.23 for to determine the tip rate to the nearest whole percent. Wha

Monica [59]

Now, if the customers left 8.23 extra, based on a percentage of the cost of the meal, namely, the 8.23 is a percent of 49.28, then

if we take 49.28 to be the 100%, how much of a percentage is 8.23?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
49.28&100\\
8.23&t
\end{array}\implies \cfrac{49.28}{8.23}=\cfrac{100}{t}\implies t=\cfrac{8.23\cdot 100}{49.28}$
