Circumference = 2πr
Circumference = 2*5 * π
Circumference = 10π or 31.4 cm
Area = πr^2
Area = π * 5^2
Area = π * 25
Area = 78.5 square cm.
I used 3.14 for PI
After doing some quick calculations, we can determine that X = −35.9
I hope this helps! :)
Floyd's contract consists of
(i) $200 per month fixed.
(i) $12 per album sold.
Let x = number of albums sold last month.
Because total earnings is $644, therefore
200 + 12x = 644
To find x, do the following:
Subtract 200 from each side.
12x = 644 - 200 = 444
Divide each side by 12.
x = 444/12 = 37
Answer:
The equation is 12x + 200 = 644.
The solution for x (number of albums sold) is 37.
Rate of change is Rise over run=3/36=1/12 inches
