7. A bicycle has wheel 28 inches in diameter. The tachometer determines the wheels are rotating at 180 RPM (revolutions per minute). A. Find the speed in inches per minute. B. Find the speed the bicycle is traveling down the road in miles per hour. (1 mile = 5280 feet) 8. In a circle of radius 9 miles, find the length of the arc that subtends a central angle of 80 degrees.

Step 1
Given: - Wheel diameter = 28 inches - Wheel rotation speed = 180 RPM The circumference of the wheel can be calculated using the formula: Circumference = π * diameter Circumference = π * 28 = 88 inches Speed in inches per minute = Circumference * RPM Speed in Show more…

A bicyclist rides down the road on a bike with wheels that have a diameter of 28 inches. She is bicycling at 16 miles per hour (5280 feet per mile). a) What is the angular speed of the wheel in radians per minute? Give an exact answer (no decimals): rad/min b) What is the angular speed in revolutions per minute? Give an exact answer in terms of rpm. c) What is the approximate angular speed in revolutions per minute? (rounded to two decimal places)? rpm
