Answer:

Step-by-step explanation:
Given
Shape: Opening of a circular vase


Required
Determine the area
This opening implies a circle; hence the area will be calculated using area of a circle.

Solve for radius (r)



Substitute 6.75 for r in

Answer:
x = k - 3
Step-by-step explanation:
Given parameters:
Gradient of the line = 5;
Coordinates; M(x, 8)
N(k, 23)
Solution:
If we use the expression for finding the slope of the line, we can solve this problem;
Slope = 
where
x₁ = x y₁ = 8
x₂ = k y₂ = 23
Input the parameters:
5 = 
15 = 5(k - x)
3= k- x
k - x = 3
Express x in terms of k;
-x = 3 - k
Multiply through by -1;
x = -3 + k
x = k - 3
Answer:
the answer I got was x>36
