Step-by-step explanation:
I had to take help from my brother for the solution as I'm not very good with solid geometry. Hope you got it and thanks for sharing questions like this. It helps me to learn more.
Answer:
true
Step-by-step explanation:
The left side 9 is greater than the right side 3, which means that the given statement is always true.
Answer: 11
step by step instructions: so you have your statement. (3/7)r+(5/8)s you then would plug in (14) for (r) and (8) for (s).once you plug these in you then simplify the statement. (3/7)*14=6 and (5/8)*8=5. so your new statement should be 6+5=11
hope this helps
Circumference = 2πr
So the circumference of the track is C = 2π .2 or .4π
3 times around the track is .4π x 3 or 1.2π - this is the answer but most teachers will want you to use 3.14 for pi.
so 1.2 x 3.14 = 3.768 km
Do you notice that I waited until the end to use the actual value of pi (3.14) in my calculations.
Keeping things in pi units until the very end saves time.
