The circumference of a circle is πd, the constant pi times the diameter of the circle.
351ft(rev/(3.5π ft)≈31.92 revolutions
Y=k/x²; substitute x=1 and y=1/8: 1/8=k. So y=1/(8x²)
When x=5, y=1/(8×25)=1/200.
Answer:
1,456
Step-by-step explanation:
The sum of n terms of a geometric sequence with first term a1 and common ratio r is given by ...
Sn = a1·(r^n -1)/(r -1)
For your series with a1=4, r=3, and n=6, the sum is ...
S6 = 4·(3^6 -1)/(3 -1) = 2·728 = 1,456
