Answer:
R=0.39789 ft
Step-by-step explanation:
For the perfectly mowed lawn, after one revolution, you want the lawnmower to be exactly one lawnmower's width closer to the pole. This implies that one lawnmower width should wrap around the circumference of the pole every revolution. So for this lawnmower we want:
2πR=2.5
⇒R=2.5/2π
R=0.39789 ft
The markup is 8%, meaning it costs 8% more.
The starting price is 100%.
Therefore, the markup is 108% of $12.
If we multiply 12 by 108% (1.08), we will get our answer of $12.96
(7 cm)*(10 cm) = 70 cm^2
The area is the product of length and width.
