OK for number 3is 70because you add the number that they give you and then subtract 36 106 and you get your answer
Answer:
Surface area of cylinder= 211.5π
Step-by-step explanation:
Given,
Height of cylinder = 19cm
Diameter of cylinder = 9cm
i.e Radius of cylinder = diameter/2 = 9/2 = 4.5cm
Surface area of cylinder = 2πrh + 2πr²
Plug corresponding values of r and h in surface are formula.
Surface area of cylinder = 2πrh + 2πr² = 2π*4.5*19 + 2π*4.5²
Surface area of cylinder = 171π+40.5π = 211.5π
Hence we get surface area of cylinder= 211.5π
-4/5 is the skip of the graph

Answer:
(1.5, 2.5)
Step-by-step explanation:
(x,y) is being multiplied by 2 to get (3,5). We need to divide it by 2 to find x and y.
3/2= 1.5
5/2=2.5
Thus, the answer is (1.5, 2.5). Hope this helped!
