For this case we have by definition, that a hemisphere represents half of a sphere.
Its volume is given by:
Where "r" represents the radius.
Substituting the data and clearing the radio we have:
![\frac {2} {3} \pi * r ^ 3 = 18 \pi\\\frac {2} {3} * r ^ 3 = 18\\r ^ 3 = 18 * \frac {3} {2}\\r ^ 3 = 27\\r = \sqrt [3] {27}\\r = 3](https://tex.z-dn.net/?f=%5Cfrac%20%7B2%7D%20%7B3%7D%20%5Cpi%20%2A%20r%20%5E%203%20%3D%2018%20%5Cpi%5C%5C%5Cfrac%20%7B2%7D%20%7B3%7D%20%2A%20r%20%5E%203%20%3D%2018%5C%5Cr%20%5E%203%20%3D%2018%20%2A%20%5Cfrac%20%7B3%7D%20%7B2%7D%5C%5Cr%20%5E%203%20%3D%2027%5C%5Cr%20%3D%20%5Csqrt%20%5B3%5D%20%7B27%7D%5C%5Cr%20%3D%203)
Thus, the radius of the hemisphere is 3 inches.
Answer:
Answer:
500 miles
Reason:
On its first flight, it flew away 1000 miles away from London but flew 500 miles towards London on its second flight.
1000 miles - 500 miles = 500 miles :)
Answer:
85
Step-by-step explanation:
13 x 13 = 169
84 x 84 = 7056
7056 + 169 = 7225
The square root of 7225 is 85 so that's your answer.
