Find the exact circumference of the circle.

a. 9 pi mm

b. 17 pi mm

c. 13 pi mm

d. 26 pi mm

The diameter is 13. It is the hypotenuse of the right triangle.
C = pi * d
C = pi * 13

Letter C

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
