Answer:
143547
Step-by-step explanation:
1) Multiply the first 2 numbers: 7 x 2 = 14
2) Multiply the first and third numbers: 7 x 5 = 35
3) Now we get 14 and 35. Add both these numbers: 14 + 35 = 49
4) Now subtract the second number that is 2 from 49: 49 - 2 = 47
5) Hence, the answer is 143547
Thanks for giving such an interesting question! Loved it!
B
The scientific notation will be Letter D
1 (anything with the exponent of 0 always equals 1)
V=pi x (r)^2 x h
V-volume r-radius h-height
V= pi x (3)^2 x 9
V= pi x 9 x 9
V= pi x 81
V= 254.47 (rounded)
Answer: 10 hours
