Answer:
706.5 cm²
Step-by-step explanation:
Surface area of the open cylinder with only one base = surface area of cylinder - area of one of the base
= 2πr(h + r) - πr²
Where,
r = 9 cm
h = 8 cm
π = 3.14
Plug in the values into the equation
Area of the open cylinder with one base = 2*3.14*9(8 + 9) - 3.14*9²
= 56.52(17) - 254.34
= 960.84 - 254.34
= 706.5 cm²
I am pretty sure y would be 79
That answer is a quadrilateral has 4 right angles. yeah

Well the wall's area is (14x3) and the door's area is (7x3) so
14x3 - 7x3 = 105
Using BEDMAS of course
