Answer:
Step-by-step explanation:
corresponds with 
This sentence is key: "At this point, he is 3 blocks from school and half way there"
<span>since 3 blocks is halfway of the trip, that means the total distance is 6 blocks </span>
<span>from the stoplight to the library must be one block, and one block took him 4 minutes </span>
<span>therefore, therefore, the total trip takes 4 * 6 = 24 minutes, or 4 * 3 = 12 minutes from the library </span>
<span>8:24 + 12 = 8:36 </span>
<span>he arrives at school at 8:36 </span>
<span>(and yes, make sure to sketch this out!)</span>
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
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
Recall that 
So, 

Substitute 2r for h in equation 1



Hence, the volume of the sphere is 14m³
