Answer: 7065 cm
Step-by-step explanation:
Find the volume as the bowl was a whole sphere and then divide the volume found by two, to get the volume of half the sphere.
(4/3) * π*(r^3) ≈ 14130 cm
14130/2 ≈ 7065 cm
This is an approximated result using π = 3.14
Answer: 20/3 or 6.67
Step-by-step explanation:
5/1÷3/4
While dividing fractions, flip to the other side to get 5/1×4/3
=20/3
You calculate the number of ways that 2 people can be chosen from 10.
The formula:
n! / r! * (n-r)! =
10! / 2! * 8! =
10 * 9 * 8! / 2 * 8! =
10 * 9 / 2 =

Answer:
4ft.
Step-by-step explanation:
So, due to the shape being a triangle you could split the triangle in two to determine the height. This means that its essentially two right angle triangles beside one another with the hypotenuse being 5 ft long and its base being 3ft long. ( because we split the base by 2 so 6/2=3) Now we can perform the pythagorem theorum to solve for the wanted side (height). The pythagorem theorum is the hyptenuse squared equals one side squared plus the other side squared but considering we do not have one of those sides (height) we must re-organize the formula. SO the formula we will be using is hypotenuse squared minus side squared equals height squared.
Therefore,
5(squared) - 3(squared) = x(squared)
25-9=x(squared)
16=x(squared)
square root of 16=x
4=x
Finally, state your results... so we could say that due to our results the height of the tent would be 4 ft long.
