Answer: 2
Step-by-step explanation:
The radius is half of the diameter.

When you're multiplying by a power of 10 such as 100, the decimal point moves two places to the right. Note that this corresponds with the number of zeroes in 100. Of course our number is going to get bigger, not smaller, which means we'd have to be going right. If we multiplied by something like 0.001, we'd also be going two places, just going smaller and to the left.
You would multiply by the reciprocal (flip the fraction)
5/3 * 24 = 40
b = 40
