The formula for the volume of a cylinder is area times height.
That is Pi x r2 x h.
You must now decide what the 10m and the 8m represents.
r = radius = half-diameter
h = height
Pi = 3.14159......
The volume of a cylinder with a height of 9m and radius of 8m is 1809.56m3

If that's the radius, use the standard formula for the volume of a sphere.If that's the diameter, divide it by 2 to get the radius; then you can use the standard formula for the volume of a sphere.

A rectangular prism with a length of 11m, width of 8m and height of 3m has a volume of 264m3
This question is too poorly worded to distinguish the radius or diameter from the height.
240 m3 - without using a calculator !
6-8m = 10m+14 -8m-10m = 14-6 -18m = 8 m = -8/18 or -4/9 in its lowest terms

The answer is 22.02 meters
Amount of HCl is 500cm^3 of .8M HCl = .8 x 500/1000 = 0.4 mol. Volume of 10M acid to give 0.4 mol = .4/10 = 0.04dm^3 = 40cm^3 Add 500 - 40 = 460 cm^3 of water. Caution : 10M HCl is highly corrosive and should be handled with care.
For the ladder with the length of 8m 8.37m from the wall For the ladder with the length of 10m 10.44m from the wall
m=-21/2 or m=-10.5
It appears to be a scalene triangle from the given dimensions.
