All Questions Are Above

Answer 1

2. 5.25in

3. 3 in

4. 81.68 or 82

Explanation:

The first two are basically multiplication and division. radius is half the diameter, and diameter is the whole of radius. the circumference is 3.14 or
`\pi` x diameter

so you need to add the radius (13) by itself (13+13) to get the diameter (or 13*2) then multiply by 3.14159. (26*3.14159 = 81.68) and if you need to round its 82.
