How far a wheel with a radius of 9 cm travel in three revolutions?
To find the distance a wheel travels in three revolutions, first calculate the circumference of the wheel using the formula (C = 2\pi r). For a radius of 9 cm, the circumference is (C = 2\pi \times 9 \approx 56.55) cm. In three revolutions, the wheel would travel (3 \times 56.55 \approx 169.65) cm. Thus, the wheel travels approximately 169.65 cm in three revolutions.
How many revolutions will a car wheel of diameter 60 cm make as the car travels a distance of 5 km?
That the formular for the circumference of a circle (pii D)The answer should be 4.254
A bicycle wheel makes 5000 revolutions in moving 11kmWhat is the radius of the wheel?
To find the radius of the wheel, we first calculate the circumference of the wheel using the formula: Circumference = 2 * π * radius. Since the wheel travels a distance of 11 km in 5000 revolutions, each revolution covers a distance of 11 km / 5000 = 0.0022 km. The circumference of the wheel is twice the distance covered in one revolution. Thus, we have Circumference = 2 * 0.0022 km = 0.0044 km. By setting up the equation 0.0044 km = 2 * π * radius, we can solve for the radius as 0.0044 km / (2 * π) ≈ 0.0007 km, or 0.7 meters.
The earth completes one when it travles around the sun?
The Earth completes a revolution when it travels around the sun.
A vehicle has wheels which are 3.20 feet in diameter.If the vehicle travels on these wheels at a constant rate of 60 mph then how many revolutions does one wheel make in one minute?
Diameter = 3.2 ft. Circumference = 3.2 ft * pi = 10.05 ft. 1 min * 60 mph = 1 mile 1 mile = 5280 ft. # of revolutions = Distance traveled / Wheel Circumference
A flywheel 12ft in diameter makes 80 revolution per minute?
To find the linear speed of the flywheel, first calculate its circumference using the formula (C = \pi \times d), where (d) is the diameter. For a 12 ft diameter, the circumference is approximately (37.7) ft. At 80 revolutions per minute, the linear speed is (80 \times 37.7 \approx 3016) ft/min. Thus, the flywheel travels about 3016 feet per minute.
What is the distance traveled by a boy who walks on a circular track and reaches back to the starting point often completing one round?
The distance traveled by the boy would be the circumference of the circle, which is calculated using the formula: Circumference = 2πr, where r is the radius of the circle. When the boy completes one round on the circular track, he travels a distance equal to the circumference of the circle.
If the length of the minute hand of a clock is 5cm how can you calculate its speed?
The minute hand traces its path around the clock once in an hour. The distance travelled by the tip of the hand in this time is 2 x pi x 5cm.The speed is then 10pi cm/hour, which is 8.73 x 10-5 ms-1.
How many revolutions in seconds does light travel 1 mile?
None. It's a trick question. Light travels in firsts.
How many revolutions per minute are the wheels of a bicycle turning if the diameter is 26 inches and you are traveling at a speed of 10 miles per hour How many r?
To solve, you need how far is travelled in 1 minute and the circumference of the wheel (in the same units) which gives how far the wheel travels in one revolution; then dividing the former by the latter will give the revolutions per minute: I'll work in inches: There are 63360 inches in 1 mile and 60 minutes in 1 hour, thus: 10mph = 10 x 63360 ÷ 60 inches per minute = 10560 ipm circumference = π x diameter = 26π inches ⇒ revolutions per minute = 10560 ipm ÷ 26π ins ~= 129.3 rpm
If a wheel with a diameter trvaled a full rotation how far would it get?
To determine how far a wheel travels in one full rotation, you can calculate the circumference of the wheel. The circumference is given by the formula (C = \pi \times d), where (d) is the diameter. Therefore, if you know the diameter of the wheel, simply multiply it by (\pi) (approximately 3.14) to find the distance traveled in one full rotation.
What is the distance the equator travels on land?
The distance around the Earth at the Equator, its circumference, is 40,075 kilometers (24,901 miles).
