Mae is checking her bicycle on stand. Bicycle's wheel has radius of 36cm and its center is 52cm above the ground Mae is rotating the wheel at constant speed of 5pi/6 radians per second.
A) describe function using sine function. where h is the height in feet and t is time in minutes
b)find H(t)=3.5 sec. round your answer to nearest tenth in cm.
Can yall help me to do this and show me the step

yes h is the height, also i just copied off what the question said so i really don't know

I would assume that h refers to the height above ground of a point on the circumference of the wheel. If you draw the situation you will see that it varies between 16cm and 88cm. As the wheel turns the height from the centre will vary as a sine function of the angle A at the centre multiplied by the radius. So h = 56 + 36sinA. But you want h as a function of time. Well you are given the connection between A and t.

Height of what? Is h different from H?
