Question 4 As you become more fit, you should see an increase in your resting heart rate
True or false

That's false.  It's just the opposite.  As you become more fit, your heart becomes able to accomplish more with each beat, so your resting heart rate DEcreases.

We have that the surface of the cylinder is given by 2prh. The diameter is 0.1 μm, so the radius is 0.05 μm. Hence, substituting we get that the total surface area is 0.314 μm^2=2*0.05*1*3.14.

The surface of a hemisphere is half the surface of a sphere. The surface of a sphere is: 4pr^2. Hence, the hemisphere has an area of 2pr^2.  Substituting now again, we get:
μ.
This is the area of the top.

We can add these two areas to find the total area.
