Answer:
408.46cm^2
Step-by-step explanation:
Given data
Height= 13cm
Diameter= 10cm
Radius= D/2= 10/2= 5cm
The area of the curved surface will be = 2πr × h = 2πrh
substitute
Area of the curved surface = 2πrh= 2*3.142*5*13
Area of the curved surface = 2πrh= 408.46cm^2
Hence the area of the curve surface is 408.46cm^2
0.25
-9/6 divided by 3/-2 = 0.25
i am sorry
your question is unclear
x+2y=4
-x -x
2y=4-x
divide by 2 to get y by it's self
y=2-(1/2x)
-2y -2y
x=4-2y
i don't know if u want me to help u with the second one but i did it the first one
