(3 + 12) - 3² + 8 · 2 ÷ 4 (7 + 5) · 2 - 4² ÷ 8 + 3

3(8 + 2) - 6² ÷ 9 + 8

6 + (5 - 3) · 3² ÷ 9 – 7

(6 + 4)² ÷ 4 – 8 + 6 · 8

16 + 3(8 + 2) + 6² ÷ 9

6(13 – 8) - 6² ÷ 4 + 11

7 + (16 + 8) - 5² · 4 ÷ 20

can you solve all 8 questions with shown work all steps/ sorry the title is also a question

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

do i do it on a graph?

step-by-step explanation:

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
