Answer:
Radius of the sphere = r
<u>Volume of sphere:</u>
Radius of the hemisphere = 2r
<u>Volume of the hemisphere:</u>
- V₂ = 1/2×4/3×π(2r)³ = 1/2×8×4/3πr³ = 4V₁
The volume of the hemisphere is 4 times greater than the volume of the sphere
I think we all know it's A XD

Answer:
<em>0.08192</em>
Step-by-step explanation:
Given 50, 20, 8, ...
The sequence is geometric in nature
The nth term of the geometric sequence is exoressed as;
Tn = ar^{n-1}
a is the first term = 50
r is the common ratio = 20/50 = 8/20 = 2/5
n is the number of term = 8 (since we need the 8th term)
Substitute
T8 = 50(2/5)^{8-1}
T8 = 50(2/5)^7
T8 = 50(128/78,125)
T8 = 0.08192
<em>Hence the 8th term is 0.08192</em>
