It is important when converting from square feet to square inches to remember to multiply twice. 166.47 times 12 times 12.
Therefore the solution is 23971.68 square inches.
Given:
Right triangle XYZ has right angle Z.

To find:
The value of
.
Solution:
We know that,



For a triangle, all trigonometric ratios are positive. So,

It is given that
. After substituting this value in the above equation, we get




On further simplification, we get


Therefore, the required value is
.
There are 12 tickets needed. Just add all the 4's together.
The lateral surface area of a cylinder is:
a=2πrh, we are told that r=1.8ft and h=4ft so
a=2π(1.8*4)
a=2π(7.2)
a=14.4π ft^2
a≈45.24 ft^2 (to nearest hundredth of a square foot)
