The answer is 6.5 because of the angle that is used
Answer:
The answer to your question is the letter B. 27
Step-by-step explanation:
Data
The Radius of large sphere = 3 times the size of the radius small sphere.
The Ratio of Volume = ?
Formula
Volume of a sphere = 4/3 πr³
Process
1.- Calculate the volume of the large sphere
Vl = 4/3 π(3r)³
2.- Calculate the volume of the small sphere
Vs = 4/3 πr³
3.- Calculate the ratio
Vl / Vs = [4/3π(3r³)] / [4/3 πr³]
- Simplification
Vl / Vs = 3³r³ / r³
Vl / Vs = 27
Answer:
smaller x =-1/2
larger x = 7
Step-by-step explanation:
(x-7)(-4x - 2) = 0
Using the zero product property
(x-7)=0 (-4x - 2) = 0
x-7+7 = 0+7 -4x-2-2 =0+2
x=7 -4x =2
-4x/-4 = 2/-4
x = -1/2
