Answer:
We don’t have drawing tools, I’m sorry
Step-by-step explanation:
Brainly doesn’t have a drawing tool, sorry
4h+9
We can plug 4 into h to result in this expression:
4*4+9
16+9=
25
They give the formula as:
Surface Area =<span> (2 • <span>π <span>• r²) + (2 • <span>π • r • height)</span></span></span></span>
However the 2*PI*r^2 part of the formula is used to calculate the 2 "ends" of a cylinder. Since the problem states that you are NOT to count any of surface area of the "ends" then you only need the <span>(2 • <span>π • r • height) part of the formula.
So, r = 3 inches and height = 8 * 3 inches, the side area equals
2 * PI * r * height
2 * 3.14159 * 3 * 24 =
