Answer:
<u>The cover has diameter of:</u>
- 20 feet + 2*12 inches = 20 feet + 2 feet = 22 feet
a.
<u>Area of the pool cover:</u>
- A = πd²/4 = 3.14*22²/4 = 379.94 ft²
b.
<u>The length of the rope:</u>
- C = πd = 3.14*22 = 69.08 ft
Answer:
150.8ft²
Step-by-step explanation:
A=2πrh+2πr2=2·π·3·5+2·π·32≈150.79645ft²
Answer:

Step-by-step explanation:
im pretty sure its this smack me if im wrong
When we are having a point (x1,y1) and slope (m) then the equation of line is given by y - y1 = m (x - x1)
Here we do have following data provided they are;
Placing values in the given equation we get,




- Thus the equation of line is <u>y </u><u>+</u><u> </u><u>1</u><u> </u><u>=</u><u> </u><u>-3x </u><u>+</u><u> </u><u>6</u>
14x45=630
43×2=86
(14×45)-(43×2)= 630-86=544
there would be 544 pens left
