Answer:
Step-by-step explanation:
a) 8.23 x 10^5 move the decimal over 5 places, 319000000 is 319 million move the decimal over until there is one number on the left side --> 3.19 x 10^8
b) 3.19 x 10^8 / 8.23 x 10^5 = 387.61 roughly 388 times larger
V = π r² h
where r = 3 cm
V = 36π cm³
solve for h
plugin values into the formula:
36π = π 3² h
h = <u> 36π </u>
π 3²
h = 4 cm
40, 48, 56
8x5 is 40
8x6 is 48
8x7 is 56
I hope this helps have a good day
