Answer: 258023743333miles³
Step-by-step explanation:
Volume of a sphere = 4/3πr³.
where,
π = 3.14
r = radius = 3950
Volume of a sphere = 4/3πr³.
= 4/3 × 3.14 × 3950³
= 4/3 × 3.14 × 61629875000
= 258023743333miles³
The volume of our planet if we assume that it is a sphere with the radius 3,950miles will be 258023743333miles³
Three more than twice the number is 25
The number you're looking for is 25. Simply work backwards.
25 - 3 (three more...) = 22
22 ÷ 2 (twice the number) = 11
Answer:
Step-by-step explanation:
The easiest way to do this is to assume you don't get a 1 or 2. You make your first draw from 8.
8 * 7 * 6 * 5 = 1680
The total number of ways of drawing 4 marbles is
10*9 * 8 * 7 = 5040
P(`(1 or 2) ) = 1680 / 5040 = 0.33333
The probability of getting a 1 or 2 in 4 throws = 1 - 0.3333 = 0.66667
