Answer:
ft³
Step-by-step explanation:
First, let's figure out how to get the <em>volume </em>of a sphere from its <em>surface area</em>. If r is the radius of our sphere, then
The formula for a sphere's surface area is 
The formula for a sphere's volume is 
So to get from area to volume, we have to <em>divide the area by 3 </em>and then <em>multiply it by r.</em> Mathematically:
Before we solve for V though, we need to find the radius of our sphere. Thankfully, we're given the surface area - 
ft² - so we can use the area formula to find that radius:
And now that we have our radius, we can put it into our volume formula to find
ft³
Answer:
3
Step-by-step explanation:
For it to be a linear function, then it obeys the general form of a liner equation which is y = mx + c
Where m represents the slope and c represents the y intercept
Now let’s take the last point on the table;
and substitute the values of x and y;
we have;
10 = 2m + c. ••••••••(i)
let’s take the second to the last;
7 = m + c ••••••••••(ii)
So let’s solve both equations simultaneously
Just subtract second from first directly
This gives m = 3
Answer:
420
Step-by-step explanation:
I'd say the mode is probably also 12.
Answer:
3√2
Step-by-step explanation:
perform factorisation
√18 = √ 2 × 3 × 3
= 3√2
