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

Supposing we begin with n=1, the first few terms of this arith sequence are
5, 1, -3, -7, and so on. 4 is the common difference.
By reducing 21/30 you dived 21 and 30 by 3 and you will get 7/10. Is 7/10 larger than 2/3? If we put these fractions in decimal form we will see 7/10 turns into 0.7 and 2/3 turns into 0.667. So the answer is 21/30 is larger than 2/3.
