The letters of the word S U M M E R were placed in a bag. What is the probability of choosing an R? 3:6
5/6
33.3%
0.16

I'm asking it again cause I got an answer that had nothing in it!

not a clue

step-by-step explanation:

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

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
