Circumcerence = distance travelled in one full rotation = 2 x π x 8 = 16π
for 2 minutes and 15 seconds,
multiply 16π by 2.25 as 2 minutes is twice the distance of one rotation and 15 seconds is a quarter more
therefore answer is 36π = 113.1 inches
Well 52 divided by 8 is 6.2 so..
The answer is 7.8
Hope this helps!

Answer:
Step-by-step explanation: 3a-5b= 3(7)-5(4)
=21-20
=<u>1</u>
7-3a+5a+15=7-3(7)+5(7)+15
=7-21+35+15
=-14+50
=<u>36</u>
15a^2-17(bc)^2=15(7)^2-17(4)(-3)^2
=105^2-204^2
=210-408
=<u>-198</u>
