Answer:
7 1/3
Step-by-step explanation:
V = πr²h
V₁ = π x 4² x 11 = 176π
v₂ = π x 2² x 6 = 24π
V₁ /v₂ = 176π / 24π = 22/3 = 7 1/3
Answer:
8/20 in simplest form this would be 2/5
Step-by-step explanation:
True, angle sums are generally equal to (n-2)*180, where n is the number of sides
Answer:
x=3
Step-by-step explanation:
the volume of the prism with triangular base is 54 unit³
The base is a triangle with, base i.e 4 units and height i.e x units
Also, height of the prism = 3x
So, volume of the prism is,
And
,

Then,

As the volume is given as 54 unit³, hence
6x²=54
x²=9
x=3
The formula is right there in the question. Just write '16' in place of 'b' and write '5' in place of 'h', then do the multiplication and you have the area. / / / If you don't get 40 square mm then you have a mistake somewhere.
