30/78 simplified is 15/39
Answer:
1
Step-by-step explanation:

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)
The GCF of 2 and 4 is 2, so, divide both numbers in the ratio to find the simplified version.
2 to 4
2/2 to 4/2
1 to 2
Therefore, the answer is 1 to 2.
Best of Luck!
