Answer:
3
Step-by-step explanation:
A direct variation is of the form
y = kx
We know x and y so we can find k
81 = k *27
Divide each side by 27
81/27 = 27k/27
3=k
The constant of variation is 3
Answer:
can't see any parallelogram

Actually Welcome to the Concept of the Symmetry,
Option A.) is correct,
=> N has only the Rotational Symmetry.
Find slope (y2-y1)/(x2-x1)
(4-5)/(3-0) = -1/3
Y = -1/3x + b
5 = -1/3(0) + b, b = 5
Equation: y = -1/3x + 5
Volume of a sphere is 4/3 x pi x r(cubed)— so based on that I think it’s 2.14 cm cubed
