Find the surface area of the cylinder. Use a ~ 3.14 20 m​

1444.4 m2

Step-by-step explanation:

Surface Area = 2 * 3.14 * (R*R + R*L) = 2 * 3.14 * (10*10+10*13) = 1444.4 m2

Note .. You can Derive this  

"Surface Area = 2 * 3.14 * (R*R + R*L)"

Using Calculus by differentiating its Volume

V = 3.14 * R * R * L

or

Step-by-step explanation:

Given the problem,

Follow the PEMDAS order of operations. Start by working on the terms inside the parenthesis:

= 26 + (10 - 8) ÷ 4 + 3 × 6

= 26 + (2) ÷ 4 + 3 × 6

Next, divide 2 by 4:  

= 26 + + 3 × 6

Multiply 3 and 6:

= 26 + + 18

Add 26 and   :

=   + 18

Add   and 18. Convert 18 into fraction:

=  

= (convert by dividing 89 by 2 to get ).

Therefore, the correct answer is    or .
