Answer:
6
Step-by-step explanation:
2= 2/1
( 2/1 ) / ( 1/3 )
2x3 = 6
1x1 = 1
6/1 = 6
Answer:
254.4 in²
Step-by-step explanation:
Area of a circle is given by the formula:
Our radius is 9 so we substitute this into the equation:
π(9)² = 81π
81π = 254.4 in²
Let the length be x and the width be y:
Area=x*y=600
thus
x=600/y
Perimeter=2(L+W)
100=2(x+y)
substituting the value of x we obtain:
100=2(600/y+y)
solving for y we shall have:
50=600/y+y
50y=600+y^2
thus
y^2-50y+600=0
solving the quadratic we obtain:
y=20 or y=30
thus the length=30 ft and the width=20 ft
