HELP FAST DECENT POINTS FOR AN EASY QUESTION! Find the surface area for the following prism 9 in 12 in 3 in.

207 in^2

Step-by-step explanation:

length= 9 in

breadth= 12 in

height= 3

sa=(lb +bh +lh )+bh

     {(9 x 12) +(12 x 3) +(9 x 3)} +(12 x 3)

    {108 +36 +27}+ 36

   sa=207in^2

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a

a negative exponent is translated as follows:

so, we have
