Question 1139006
<br>
diameter 10  -->  radius 5<br>
total length = length of cylinder + radius of hemisphere = 20  -->  length of cylinder is 15<br>
A) For a sphere, surface area is {{{4(pi)r^2}}}
half of that for the hemisphere<br>
B) see above<br>
C) Lateral surface area of cylinder is {{{2(pi)rh}}}
Area of bottom of cylinder (circle) is{{{(pi)r^2}}}<br>
Fill in the measurements and do the calculations....<br>
Leave answers in terms of pi unless directed otherwise.
