For the first one: A=pi*r^2*1/8 (1/8 becuase we are finding the area of one pane)
A=pi*16/8
A=2pi
For the second one: First do the larger circle minus the smaller circle (pretend they are whole circles)
A(larger)=pi*18^2
=324pi
A(smaller)=pi*8^2
=64pi
A=324pi-64pi =260pi
Now, a whole circle is 360 degrees so 150 degrees is 5/12 of a circle. We take 5/12 of 260pi to get the answer
260pi*5/12=340.3
Answer:
$50
Step-by-step explanation:
15x18=270
1170-270=900
900/18=50
The power of 4 means to move the decimal 4 places to the right. 6.3 x 10^4
63000
Lets x = the number of songs
The product of the number of songs and $0.99 = 0.99 times x = 0.99x
The product of the number of songs and $0.99 is $7.92:
=
0.99x = 7.92
Hope that helps.
