Answer:
2000.8 m or 2km height
(π 0.07^2)×2000 = 30.78 m^3.
Step-by-step explanation:
The total surface area of a cylinder of radius 7 cm is 880 m^2. Find the height and the volume of the cylinder.
"A cylinder is flat" according to curvature theory (unlike a sphere, where triangle angles can add to more than 180°). So unwrap it and compute area as circumference times height, or height as area divided by circumference. 880m^2 / (2 π 0.07 m) gives height = 2000.8 m or 2km (!!)
The volume of a cylinder is cross section area times height. (π 0.07^2)×2000m = 30.78 m^3.
Answer:
Option 2
Step-by-step explanation:
Height of lemon tree = 8
Height of date tree = 8 x 3
On comparing, we understand that the date tree is 3 times as tall as the lemon tree.
Am not sure but I think is c
1+1=2
hope this helps, cheers-irys
I think the answers to the second column are as follows:
