How is this done?

( My first impulse was to set u=x^3, but I don't think that will get the x^2 out of the square-root )

It says: A flywheel with a 15-cm diameter is rotating at a rate of 7 radians/sec. What is the linear speed of a point on its rim, in centimeters per minute.

First off, the answer is 3150 cm/minute (according to the book). Now what I did was take the angular speed (which is the 7 radians/sec part, right???), and multiply it by the radius, which is 7.5, and then multiply it be 60 to get it from seconds to minutes. Is that the correct way to find the answer?

The second question is: A wheel with a 30-cm radius is rotating at a rate of 3 radians/sec. (Again, is the 3 radians/sec part called the angular speed?) What is the linear speed of a point on its rim, in meters per minute?

I got 54m/minute by taking the 3, multiplying it be 30, multiplying it by 60, and dividing by 100 (to get from cm to m). Is that all right? Thanks so much! I'll pick a best answer TODAY!!!!

I'm a noob but want to begin designing an EV motorcycle. I know the very basics at this stage.

To get better range, I want to use some larger 12V batteries along with lighter ones. The voltage will be regulated with a suitable controller (Alltrax 7245).

So I'm proposing:
12V 27Ah x4
12V 51Ah x2

But I've heard that batteries should be matched and have the same rating. Aside from recharging hassles, are there any other reasons?
The batteries I'd like to use are Hawker SBS30 and SBS60 absorbed glass mat types.

Thanks!
