Answer:
r = 22.3m circa
Step-by-step explanation:
We know that the perimeter of a circle can be calculated as follows:
p = 2r
So half of perimeter will be:
p/2 = r
We know that p/s = 70m, therefore:
r = 70m / = 22.3 m circa.

count only the pair numbers between 200 and 240:
200, 202, 204, 206, 208, 210, 212, 214, 216, 218, 220, 222, 224, 226, 228, 230, 232, 234, 236, 238, 240
move the decimal in 1.4 two places two the right and do the same with 3.36 then divide
A=3
2353032/99 = 23768
