Answer:

y = -0.5x + 2

Step-by-step explanation:

In order to find the equation of a line given two coordinates, you must first find the slope of the equation.

y = mx + b

To find slope (m), use the equation below:

Slope = (y2 - y1 ) / (x2 - x1 )

(2, 1)

(-2, 3)

y2 = 1

y1 = 3

x2 = 2

x1 = -2

Slope = (1 - 3) / (2 - -2) = (-2) / (4) = -0.5

y = -0.5x + b

Next, plug in one coordinate in order to solve for b:

Let's plug in the numbers (-2,3)

3 = -0.5 (-2) + b

b = 3 - 1 = 2

Line's equation =

y = -0.5x + 2

A sphere with a diameter of 16mm has the same surface area as the total surface area of a right cylinder with the base diameter
miv72 [106K]
R_{sphere}= \frac{1}{2} *16=8[mm]\\
A_{sphere}=4 \pi R^{2}\\
A_{cylinder}=2 \pi R(R+h)\\\\

4\pi R^{2}=2 \pi R(r+h)\\
 \frac{4\pi R^{2}}{2 \pi R} =r+h\\
h= \frac{4\pi R^{2}}{2 \pi R}-R=2R-R=R\\
R=8[mm]

So the answer is B. 8 mm
