What is the exact circumference of a circle with a radius of 17 millimeters?

a.
8.5π millimeters

b.
17π millimeters

c.
34π millimeters

d.
68π millimeters

The equation of a circumference is 2r. Since we know that r=17, we plug that into the formula, and get an answer of C. 34

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
