Let r and s be binary relations on a set a. suppose that r is an equivalence relation and that s is symmetric, and transitive but is not reflexive. which statement is always true for any such r and s?
(a)r? s is symmetric but not reflexive and not transitive.
(b)r? s is symmetric but not reflexive.
(c)r? s is transitive and symmetric but not reflexive
(d)r? s is reflexive and symmetric

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
