Volume = 6²π(26) - (2.1)²π(26)

             = 26(36π - 4.41π)

             = 26(31.59π)

             = 821.34π cm³

6C2 = 15 pairings. This happens twice though so it's 15 * 2 = 30 matches in one division

Then you need to do the other division, which means you have 30 * 2 = 60 games.

Then there are 6 * 6 games between the two divisions which means your total is 60 + 6 * 6 = 60 + 36 = 96 conference games

Area of the figure = 5 x 4 + 2 x (3 + 4 + 3)

                             = 20 + 2 x 10

                             = 20 + 20

                             = 40 cm²

x + 2x = 90

3x = 90

x = 30

The angle is 60

Bagels cost $1.25 = 125 cents

Cupcakes cost 50 cents

i) Two bagels cost 125 x 2 = 250 cents, or $2.50

ii) Two cupcakes cost 50 x 2 = 100 cents, or $1.00

iii) Bagels cost 125 - 50 = 75 cents more than cupcakes :)

Thank you!

I got 2268a base 11 digits... I'm not sure how you calculated it but I used Melody's answer as a guide and this is what I got?
