Q. Which formulas represent linear relationships? Select all that apply.Multi-select Choices:(A)the area of a circle, A=πr2(B)the perimeter of a regular hexagon, P=6s(C)the volume of a sphere, V=34πr3(D)the perimeter of an isosceles right triangle, P=(2+2)s
Linear Relationship Definition: Linear relationships are represented by equations where the dependent variable changes at a constant rate with respect to the independent variable. The equation should be of the first degree.
Choice (A) Area of Circle: Choice (A) A=πr2 describes the area of a circle, which depends on the square of the radius (r2). This is not a linear relationship because it involves a square term.
Choice (B) Perimeter of Hexagon: Choice (B) P=6s describes the perimeter of a regular hexagon, where P changes linearly with each change in side length s. This is a linear relationship because it involves only the first power of s.
Choice (C) Volume of Sphere: Choice (C) V=34πr3 describes the volume of a sphere, which depends on the cube of the radius (r3). This is not a linear relationship because it involves a cube term.
Choice (D) Perimeter of Triangle: Choice (D) P=(2+2)s describes the perimeter of an isosceles right triangle, where P changes linearly with each change in side length s. This is a linear relationship because it involves only the first power of s.
