For the square to fit inside the circle without touching it, the diagonal of the square needs to be less than the diameter of the circle.
Using the Pythagorean theorem we can calculate the diagonal of the square:
X = SQRT(5^2 + 5^2)
X = SQRT(25 + 25)
X = SQRT(50)
X = 7.07
The diagonal of the square is 7.07 cm, which is less than the diameter of the circle, 9cm, so it will fit .
To find the answer to this, we can use the formula for the diagonal of a square,
a
, with a being the length of the side. That meaans that the length of the diagonal is 98, which is approximately equal to 138.59.
15/7 x 5 and 2/5 x 7
75/35 - 14/35 = 61/35
The total weight being carried is
3545 +1758 +3697 = 9000 . . . . . pounds
Each ton is 2000 pounds, so together the trucks are carrying
(9000 lb) × (1 t)/(2000 lb) = 4.5 t
Altogether, the 3 trucks are carrying 4.5 tons of topsoil.
