Answer:
1507m²
Step-by-step explanation:
Given parameters:
Radius of cylinder = 12m
Height of cylinder = 8m
π = 3.14
Unknown:
Surface Area of cylinder = ?
Solution:
The surface area of any body is the sum of all the area that covers a body.
For a cylinder, the surface area is given as;
SA = 2πr² + 2πrh
Where SA = Surface Area
r = radius of cylinder
h = height of cylinder
Now input the parameters in the given equation and solve;
SA = (2 x 3.14 x 12²) + (2 x 3.14 x 12 x 8)
SA = 904.32 + 603.264
SA = 1507.584m² = 1507m²
Example 1 – Solve: 3x3 = 12x
Step 1: Write the equation in the correct form. In this case, we need to set the equation equal to zero with the terms written in descending order.
 3x^3-12=0
Step 2: Use a factoring strategies to factor the problem.
 3x(x^2-4)=0
3x(x+2)(x-2)=0
Step 3: Use the Zero Product Property and set each factor containing a variable equal to zero.
 3x=0 or x+2=0 or x-2=0
Step 4: Solve each factor that was set equal to zero by getting the x on one side and the answer on the other side.
 x=0 or x=-2 or x=
