Answer:
radius of the hemisphere = 9 cm approx
Step-by-step explanation:
Volume of hemisphere =
1527.4 =
=
=
= 729
r =
r = 9 cm approx.
Rule of trigonometric functions:-
sin a = cos(90 - a)
Here a = 90°.
sin 90 = cos (90 - 90)
1 = cos 0.
cos 0 = 1.
So the cos 0 = 1.

Blue (b): 1500
Green (g): 1000
Purple: (1/2)Green = (1/2)1000 = 500 THIS INFORMATION IS NOT NEEDED!
b/g = 1500/1000 = 1.5
