Answer:
736 N
Step-by-step explanation:
Area of the rectangular tile=length*breadth
=1.6*2.3 sq. metres
=3.68 sq . metres
Given, Maximum pressure sustainable by the tile=200N/sq.metres
Thus, the maximum force that can safely be applied to the tile=Pressure*Area
=200*3.68 N
=736 N
nine divided by five to the sixth power is 0.000576
Since A (area of circle = C) is given = 148
Where we assume:
Y represents radius of the circle (r)
X represents diameter of the circle (D)
Pi (π) = 3.14
A = 2 * π * y
148 = 2 * 3.14 * y
148 = 6.28 * y
y = 148/6.28
So, y = 23.56
D = 2 * y
D = 2 * 23.56
So, D = 47.12
Assume A is unknown (not given as 148)
A = π * y^2
A = 3.14 * (23.56)^2
A = 3.14 * 47.12
So, A = 147.95 (approx. A = 148)
