Answer:
<h2>See the explanation.</h2>
Step-by-step explanation:
Here, an equation of straight line is given.
The equation is
.
If you put x = 0, in the above equation, you will get y = 0.
Hence, the equation passes through (0, 0).
Again if we put, x = 1 in the above equation, we will get y = - 1.5.
It means the equation also passes through (1, -1.5).
Joining these two points, you can graph the straight line.
R/2 - r. i think... I'm not so sure. You divide 2 and r then subtract r.

Answer:
True.
Here, radius of the sphere = radius of the cylinder = r
Diameter of the sphere = height of the cylinder = 2r
Surface area of the sphere = 4πr2
Curved surface area of the cylinder = 2πr (2r) = 4πr2
