K(3)-k(2) because if you studied for 8 hours or 7 hours it is almost like the same that you know all of them but 3 hours or 2.
To calculate the circumference multiply the radius by 2 to get the diameter. Multiply the result by π, or 3.14 for an estimation.
3.22x 2 = 6.44
6.44x π= 20.23185668911827
rounded to the nearest ten: 20.2
Answer:
