Answer:
1
Step-by-step explanation:
The lateral area of a cylinder is ...
LA = 2πrh
The total area is that added to the areas of the two circular bases:
A = 2πr² +2πrh
We want the ratio of these to be 1/2:
LA/A = (2πrh)/(2πr² +2πrh) = h/(r+h) = 1/2 . . . . cancel factors of 2πr
Multiplying by 2(r+h) gives ...
2h = r+h
h = r . . . . . subtract h
So, the desired ratio is ...
h/r = h/h = 1
The ratio between height and radius is 1.
3/7 is equal to 9/21 because when you simplify 9/21 you can divide both 9 and 21 with 3 so you would get 3/7

Step-by-step explanation:
Answer:
22.05in^2
Step-by-step explanation:
Formula for area of a triangle:
(base × height) / 2
(bh)/2
(12.25 × 3.6)/2
44.1/2
22.05
When finding the area, the units will always be to the second power because we are multiplying them
in × in = in^2
