On Tuesday we did:

 = 3.14

TSA = 2r^2 + 2rh - 2r^2 + 2rh
= 24^2 + 24(20) - 23^2 + 23(20)
= 216 + 80 - 29 + 260
= 32 + 160 - 18 + 120
= 296 cm^2
= 929.91 cm^2

TSA = 10^2
= 10(3^2)
=10 (9)
=90 cm^2


a^2+b^2=c^2
6^2 + 3.5^2 = c^2
36 + 12.25 = c^2
48.25 =c^2
6.95 m^2

TSA = lw
= 2(8) (6.95)
= 2 (55.6)
= 111.2 m^2

111.2 x 10000 = 1112000
111.2/300 = 3707
I need 3707 tiles

Incase you don’t know how I got 10000
1m^2 = 100 x 100 cm
= (100 cm^2)
= 10000 cm^2
