A cake has a circumference of 25 1/7 inches. What is the area of the cake? Use 22/7 to approximate pi. Round to the nearest hund

s344n2d4d5 [400]

Answer:

Step-by-step explanation:

$Circumference=25\frac{1}{7}\\\\\i \pi*d=\frac{176}{7}\\\\\frac{22}{7}*d=\frac{176}{7}\\\\d=\frac{176*7}{7*22}\\\\d=8$

r = 8/2 = 4 inches

Area=πr²

$=\frac{22}{7}*8*8\\\\=\frac{1408}{7}\\\\=201.14 inches^{2}$

Troy signed up for a new cell phone plan which charges him a fee of $40 per month, plus $0.05 for each text message that he send

nataly862011 [7]

He can send 600 messages.
40+0.05x=70
-40+0.05x=70-40
0.05x=30
So divide 30 by 0.05
and you get 600.

The diameter of each wheel of a bicycle is 27 inches. If you are traveling at a speed of 20 miles per hour on this bicycle, thro

klasskru [66]

Notice, you've got a diameter in inches
and a linear velocity in miles
thus, you'd need to convert first

$\bf v=rw\implies \cfrac{v}{r}=w\qquad 
\begin{cases}
v=\textit{linear speed}\\
r=radius\\
w=\textit{angular speed}\\
 --------------\\
v=20\frac{mi}{h}\\
r=\frac{diameter}{2}=\frac{27}{2}
\end{cases}
\\\\
\textit{now, converting 20miles to inches}
\\\\
\cfrac{20mi}{h}\cdot \cfrac{5280ft}{mi}\cdot \cfrac{12in}{ft}\implies \cfrac{20\cdot 5280\cdot 12\ in}{h}\impliedby v
\\\\\\
\cfrac{1267200\frac{in}{h}}{\frac{27}{2}in}=w$

now, whatever that is, you'll need to divide it by a revolution, recall, a revolution is $2\pi$
thus $\bf \cfrac{\qquad \boxed{\cfrac{1267200\frac{in}{h}}{\frac{27}{2}in}}\qquad }{2\pi }=revolutions$
