Surface area= combined area of the figure;
Surface area of right cylinder: 2πrh+2πr² (the first part represents area of rectangle and the second represents the area of the circles)
SA=2π(4/2)(12)+ 2π(4/2)² <-- radius is half the diameter
SA=175.9 yd²
<span>Hope I helped :) </span>
1540.5 .
V=PI*R^2*H/3=3.14*9.5^2*5.433=1540;5
(So “/” will basically mean divide)
450/3000=0.15
0.15*100=15% rate
