Here are some simple equations that can be a life saver with this stuff :
vol of a sphere =

Circumference =

sorry this might not be very helpful. I haven't don't this since last year. You basically have to work backwards. so plug in 972 for V and then do (3/4)×3.14.
then take the answer u got for ^^ and divide it by 2? not sure.
Area = Length x Height
Area = 5.4 x 5.4
Area = 29.16
6.25 liters best thing to do is when you put the question put the answers too
Find angleK:
Angle k = 180-45-85 = 50
Both triangles have an angle equal to 85 and 45, which makes the 3rd angle in both triangles equal to 50
Because all three angles are the same the triangles are similar.
