Answer: 1. HA cannot be a reason to show given triangles are congruent as it is not given that they have an acute angle common in both the triangles.
2. HL can be a reason to show given triangles are congruent as the triangles are right triangle with equal legs and hypotenuse.
3. SAS can be a reason to show given triangles are congruent as there are two congruent sides in both triangles and included angles ∠A=∠D=90° [right angle].
4. LA cannot be a reason to show given triangles are congruent as it is not given that they have an acute angle common in both the triangles.
5. AAS cannot be a reason to show given triangles are congruent as it is not given that they have two angles common in both the triangles.
6.SSS can be a reason to show given triangles are congruent as it is shown that all the sides of one triangle is congruent to the other.

1 load of stone equals 1/6 ton
The radius of right circular cylinder is 4 feet
<em><u>Solution:</u></em>
Given that volume of a right circular cylinder is represented by:
Where, "r" is the radius of base in feet
And "h" is the height of cylinder
Given that volume is 144 Pi cubic feet
height = 9 feet
To find: Radius of cylinder
Substitute the given values in formula,
Thus radius of right circular cylinder is 4 feet
The diameter of the circle is 15.99cm.
