Answer:
32π is the volume of the larger sphere
Step-by-step explanation:
The volume of a sphere is V = 4/3πr³. The smaller sphere is V = 4π. This means r³ divided by 3 was 1. So r³ = 3. For the larger sphere, substitute r = 2r into the volume formula.
V = 4/3πr³
V = 4/3π(2r)³
V = 4/3π8r³
We know from the previous problem that r³ = 3.
So the volume formula simplifies to V = 4π(8) = 32π
Answer:
8
Step-by-step explanation:
m2 - 2mn + n2 ,m = -2 and n = 4
= -2( 2 ) - 2( -2 )( 4 ) + ( -2 )2
= -4 + 4( 4 ) - 4
= -4 + 16 - 4
= 8
Answer:
11.968
Step-by-step explanation:
2/3 x * x = 864
(2/3) x^2 = 864
x^2 = 864 * (3/2) = 1296
x = + sqrt 1296 = 36
length is 36 feet
Model rule is: (+)(-)= -
and the product is -520
