Calculate the circumference of the circle if its radius is 25 cm. Express the result in meters. - Bicycle wheel
What is the diameter in centimeters of the wheel of a bicycle if it turns 2000 times on a track 4082 m long - Merry-go-round angular velocity
Calculate the magnitude of the angular velocity of the seat of a merry-go-round moving in uniform motion in a circle with an orbital period of 0.2 minutes. - Circle radius meters Calculate the radius of the circle if its diameter is 16.2 cm. Express the result in meters.
- Round table
The round table has a diameter of 78 cm. A tablecloth should be sewn on it, extending around the table by 10 cm. How many centimeters of ribbons need to be bought for edging? - Two gears
The two gears fit together. The larger gear has 32 teeth. The smaller gear has 20 teeth fewer. How many times does turn a smaller gear if the bigger gear turns three times? - Diameters of circles
How many percent of the area of a larger circle is a smaller circle if the smaller circle has a diameter of 120 mm and a larger one has a diameter of 300 mm? - Coin
How many 5-cent coins must be put in a row so that the next 5-cent coins after them (above) are rolled on its axis? - The crane
The construction crane has a 20m long arm. What construction area in ares can it handle from this crane if it rotates around its axis? - Two waves
Two waves are out of phase by 26°. If the period of the waves is 6 seconds, what is the time difference between the waves? Give your answer in seconds to 2 decimal places. - One ball
The baker can stretch one ball of dough into a circle to make a pizza. After the pizza is cooked, it is cut into eight equal slices. How many slices of pizza can you make with three balls of dough? Solve this problem any way you choose. - Flywheel
The flywheel turns 450 rev/min (RPM). Determine the magnitude of the normal acceleration of the flywheel point, which is 10 cm from the rotation axis. - Clock hand angle
What is the angle of the clock hands: a / at 16 hours 15 minutes b / v 8 hours and 4 minutes - Acceleration of point
