Answer:
Answer:
835.29 Hz
Explanation:
When moving towards the source of sound, frequency will be given by
f*=f(vd+v)/v
Where f is the freqiency of the source, vd is the driving speed, v is the speed of sound in air, f* is the inkown frequency when moving forward.
Substituting 800 Hz for f, 340 m/s for v and 15 m/s for vd then
f*=800(15+340)/340=835.29411764704 Hz
Rounded off, the frequency is approximately 835.29 Hz

Answer:
1048.32 or 432 pi
Step-by-step explanation:
12*12=144
144+(4/3 pi *6^3)
6*6*6=216
216*4/3pi=864/3
864/3=288
288*3.14(pi)=904.32
904.32+144=1048.32
(If you have the pi symbol the answer is 144+288=432pi)
