Answer:
y = 1.6 x
y = 24
Step-by-step explanation:
The general equation of a direct variation is
y = k x
In this case
x = 10
y = 16
y = k*x
16 = 10*k
16/10 = k
k = 1.6
y = 1.6x
================
Let x = 15
y = 1.6 * 15
y = 24

distribute and simplify if needed, see what you get
Answer:
The total surface area of a cylinder is equal to the sum of areas of all its faces. The total surface area with radius ‘r’, and height ‘h’ is equal to the sum of the curved area and circular areas of the cylinder.
TSA = 2π × r × h + 2πr2= 2πr (h + r) Square units
