Answer:
343π
Step-by-step explanation:
To find the volume of a cone, we have to use this formula
× π × r² × h
Where 'r' is the radius and 'h' is the height
Let's start putting in the value's
We have diameter but in the formula we need the radius so we half the diameter to get the radius so 14 ÷ 2 = 7
× π × r² × h
× π × 7² × 21
→ Simplify the expression
× π × 49 × 21
→ Simplify it further
343π
Given the function :
We need to find each missing value
Given x = -3 , -2 , -1 , 2 , 7
So, substitute with each value of x to find the corresponding value of f(x)
So, there is no value for f(x) at x = -3 (the function undefined because the square root of -1)
the graph of the function and the points will be as shown in the following image :
1) Let's write out both expressions subtracting 4m²+2mn+8n² from 2m²+6mn+2n²
2) Note that when we subtract 4m^2 + 2mn + 8n^2 from 2m^2 + 6mn + 2n^2 we need to swap the sign by placing -1 outside the parentheses and then combine like terms adding those terms algebraically.
