The formula for finding the area of cylinders is TTr^2 + 2TTrh.
(TT represents pi)
Step 1.
Form the equation.
TT(25)+ 2TT(45)
Step 2.
Simplyfy the equation.
25TT + 90TT
* Here you can have the answer in two forms:
- in the form of pi
-in the form of a regular number
Step 3.
(25*3.14)+(90*3.14)
78.5 + 282.6
Area = 361.1 units ^2
or
Area = 115TT units ^2
