Answer:
506 square inches
Step-by-step explanation:
length=22 inches
breadth=23 inches 
area=length *breadth
area=22*23=506 squareinches

Answer:
–13
Step-by-step explanation:
<h2>—Math </h2>
h(x) = –x –4
h(x) = 9
–x –4 = 9
 –x = 9 + 4
 –x = 13
 x = –13

Answer:
The volume of the sphere is 14m³
Step-by-step explanation:
Given
Volume of the cylinder = 
Required
Volume of the sphere
Given that the volume of the cylinder is 21, the first step is to solve for the radius of the cylinder;
<em>Using the volume formula of a cylinder</em>
The formula goes thus

Substitute 21 for V; this gives

Divide both sides by h


The next step is to solve for the volume of the sphere using the following formula;

Divide both sides by r

Expand Expression

Substitute 



Multiply both sided by r

 ------ equation 1
 ------ equation 1
From the question, we were given that the height of the cylinder and the sphere have equal value;
This implies that the height of the cylinder equals the diameter of the sphere. In other words
 , where D represents diameter of the sphere
 , where D represents diameter of the sphere
Recall that 
So, 
 
Substitute 2r for h in equation 1



Hence, the volume of the sphere is 14m³
