The formula for the area of a circle is: 3.14 (pi) times the radius squared. A circle with a 40 mile radius would have an area of 3.14 x 40 x 40 = 5024 square miles.
Exactly 40 miles. Changing from lower case to upper case does not alter the distance!
80 pi inches
There are 40 acres in 1/16th of a square mile 1 square mile = 640 acres
One mile (5,280 feet).
The formula for the area of a circle is: 3.14 (pi) times the radius squared. A circle with a 40 mile radius would have an area of 3.14 x 40 x 40 = 5024 square miles.
40 mph = 40 miles in one hour or 0.6666666r miles per minute. 40 miles an hour = 2/3 mile a minute An hour per 40 miles = 1.5 minutes a mile = 90 seconds a mile
You're talking about circular areas.-- The area of a circle is (pi) x (radius)2 .-- The area of the 4-mile radius is (pi) x (4)2 = 16 pi square miles-- The area of a circle is proportional to the square of its radius.So the area of the 40-mile radius is (10)2 = 100 times the area ofthe 4-mile radius = 1,600 pi square miles.The larger circle has (99 times the area of the 4-mile radius) more areathan the smaller circle has.(99) x (16 pi) = 1,584 pi = 4,976.3 square miles more than the smaller circle.
1 square mile = 640 acres ⇒ 40 acres = 40 ÷ 640 sq miles = 1/16 sq mile = 0.0625 sq mile
There are 0.003125 miles in one rod. Therefore, 40 miles is equal to 40 x 0.003125 = 0.125 miles.
There are 5280 feet in one mile. Therefore to get amount of feet in miles, value of miles has to be multiplied by amount of feet in one mile: 40 miles = [miles] * 5280 = 40 * 5280 = 211200 feet
1 mile is 5280 feet. So, 40 miles per hour is the same as 211,200 feet per hour.
There are 1760 yards in one mile. Therefore, 40 miles is equal to 40 x 1760 = 70400 yards.
The second one.
1 mile = 1.60934 km So 40 miles = 64.3738 km
40 miles
40 meters is 0.025 mile.
