Answer:
are the values of a or b given?
Step-by-step explanation:
Answer:
h = 9x
Step-by-step explanation:
Given: i. for the cylinder, base radius = 2x cm, height = h cm
ii. for the sphere, radius = 3x cm
iii. volume of the cylinder = volume of the sphere
volume of a cylinder is given as;
volume = 

h
where: r is its base radius and h the height
volume of the given cylinder = 
x
x h
= 
x 4
x h
= 

h
volume of a sphere = 


where r is the radius.
volume of the given sphere = 
x 
= 
x 9 
= 12

Since,
volume of the cylinder = volume of the sphere
Then we have;


h = 12

4
h = 36

subtract
from both sides
4
h = 36
x
divide both sides by 4
h = 
= 9x
h = 9x
Answer:
x=26
Step-by-step explanation:
1/3(x-2)=1/5(x+4)+2
x-2=3/5x+42/5
5x-10=3x+42
5x-3x-10=42
5x-3=42+10
2x=42+10
2x=52
x=26
Answer:
It is a quadrilateral.
Step-by-step explanation:
Quadrilateral is a 4-sided shape where the total angles is 360°.
So when you add up all the angles, you will get 360°.
