Answer:
The radius is 0.398 feet to produce a perfect lawn for the lawnmower.
It is given that the width of the lawnmower is 2.5 feet and the length of the rope is 25 feet.
It is required to calculate the radius (R) of the pole that will produce a perfect lawn.
What is a circle?
It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).
We have,
Width of the lawnmower = 2.5 feet
Length of the rope = 25 feet
For the perfectly mowed lawn, it means the lawnmower width which is 2.5 feet must wrap the pole with radius R, mathematically:
The perimeter of the pole = width of the lawnmower
2πR = 2.5
R = 0.398 Feet ( π = 3.14 )
Thus, the radius is 0.398 feet to produce a perfect lawn for the lawnmower.
Answer:
-10 =v
Step-by-step explanation:
-13 = v/10 - 12
Add 12 to each side
-13+12 = v/10 - 12+12
-1 = v/10
Multiply each side by 10
-1*10 = v/10 *10
-10 =v
4 laps x 2 miles = 8 miles total
8 miles x 4 days = 32 total miles per week
208 / 32 = 6.5 minutes per mile
Count how much spaces from one point on the end of the line to the other.
Line VU has 9 units
Line VW has 12 units
Line UW has:
a² + b² = c²
9² + 12² = c²
81 + 144 = c²
c² = 225
√c² = √225
c = 15
Line UW has: 15 units
Now add all the units together to get the perimeter:
9 + 12 + 15 =
21 + 15 =
36
36 is your answer
