Please Help me!!

The answer would be E= 27 miles
You would start out by figuring out how many hours it would take him to swim by dividing 6/2 to get 3 then you would find out how long it would take him to run by dividing 15/6 to get 2.5 and you would add that to the 3 to get 5.5 and subtract that by 7 to get 1.5 which is how long he will have to complete leg 3 so you would take 18x1.5 to get 27 mph

Alla [95]

Answer:

$v = \frac{4}{3} \pi {r}^{3 } \\ 904.32 = \frac{4}{3} \times 3.14 \times {r}^{3} \\ {r}^{3} = \frac{3 \times 904.32}{4 \times 3.14} = 21.57 \\ r = 2.78$

then Radias equal to 5.5676
