Answer:

57%

Step-by-step explanation:

the table shows the following:

test scores for Test 1 = 62, 62, 66, 70, 70, 70, 78, 82, 82, 86

test scores for Test 2 = 68, 72, 72, 72, 72, 76, 80, 80, 80, 84, 88, 88

there are 7 tests with scores greater than or equal to 70 on test 1

there are 11 tests with scores greater than or equal to 70 on test 2

the percent change is the difference of the two amounts, 7 and 11, divided by the original amount, 7

4/7 = 57%

I am Lyosha [343]
U=\pi (r+h) \\\\ 16 \frac{1}{2}= \frac{22}{7}\cdot (r+2) \\\\ \frac{33}{2} : \frac{22}{7}=r+2 \\\\ \frac{\not 33}{2}\cdot \frac{7}{\not 22}=r+2 \\\\ \frac{3}{2} \cdot \frac{7}{2}=r+2 \\\\ \frac{21}{4}=r^{(4}+2^{(4} \\\\ 21=4r+8 \\\\ 4r=21-8 \\\\ 4r=13 \\\\ \boxed{r=\frac{13}{4}}
