The ratio of the lengths is 75 : 25 or 3 : 1
The ratio of and area is the square of this: ie 9 : 1 or 75^2 : 25^2
(In working out the area the radius is squared)
The ratio of the volumes is the cube of this: ie 27 : 1 or 75^3 : 25^3
(In working out the volume the radius is cubed)
Hopefully this explains it
Since it says less than, the 5 would be the second part of the expression
= 3L - 5
Hello!
Your answer would be C.
Multiply 3 x 8 x 5 and 2 x 5 x 6 and add both products together and you get 120 cm3.
Hope it helps you :)
