Answer:
Solution given:
radius [r]=2cm
height [h]=8cm
total surface area of cylinder=?
we have
total surface area of cylinder=2πr²+2πrh
- 2πr(r+h)
- 2π*2(2+8)
- 40π or 125.66cm²
<u>total surface area of cylinder</u><u>40π or 125.66cm²</u><u>.</u>
-b/2a is the axis of symmetry formula.
To solve those 4 questions, find the values of a and b (coefficients of ax^2 and bx term) and substitute them into the formula.
Hope this helps!
