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)
